The topic of Super Bowl 56 prop bets have already been touched on in the SUPER BOWL LVI - ESTIMATED ODDS... thread. However, I think the topic merits its own thread. Let's save the other thread for discussion of the game in general, especially the game winner and total points.
That said, let me introduce the 2022 William Hill Prop Packet. This is a 14-page PDF document of their props and what are probably their opening lines.
The question for the poll is which props will you probably bet?

Overtime, safety, 2pt conversion.

Let's start with a bet I often make, over/under 3.5 field goals scored in game.
The William Hill lines (see prop 287) are:
Over 3.5 +120
Under 3.5 -140
The following table shows the average number of field goals made per season the last three seasons.
Source: ESPN.
Note the average field goals per game increases by 0.04 per season. That said, I'm going to use the 2021 season average of 3.213235294 as the average for the Super Bowl.
The following table shows the probability of any given number of field goals, assuming the total follows the Poisson distribution. In other words, assuming the time between field goals follows the exponential distribution.
Adding the probabilities for 0 to 3, we get a probability of under 3.5 of 0.59957458. That makes the fair line on the under -150. That said, saying -140 I would say is a good bet. If you wait, you may find better than that as the square bettors love to bet the over on EVERY prop.

Wiz, shouldn’t your analysis use median field goals per game rather than mean field goals per game with an assumed Poisson?
Maybe median data not very available?

Point well taken, but I'm fine with the mean. Besides, I would probably have to look at every individual game to get the median.

There are three of them that I like:
Opening kickoff will not be a touchback (+170)
Last play of the game will not be a QB rush/keeper/kneeldown (+170)
There will not be four unanswered scores (conversions do not count as scores; safeties not on conversions do) (-320)
Also, throw a buck or two on:
Successful onside kick (+1100)
Opening kickoff will not be a touchback (+170)
Last play of the game will not be a QB rush/keeper/kneeldown (+170)
There will not be four unanswered scores (conversions do not count as scores; safeties not on conversions do) (-320)

Probably good news for you that I disagree on 3 of your picks.
1. Opening kick will be a touchback.
2. Kneeldown is how it ends.
3. I agree on no 4 unanswered scores. No big blowout here.
4. I will give you 11-1 odds on 'successful onsides kick'. The stupid new rules basically limiting your guys ability to line up on the side your kicker is kicking to makes it so hard for there to be a successful onside kick. I'll go as high as my $220 against your $20 if you want.

So Caesars has these offers...
1. Bet $100 on any SB same game parlay that gets to at least +1000, and if you win, in addition to your winnings you get an extra free bet of $560. You can only do this for your first SB parlay bet.
2. Bet $10 each on 10 separate SB props, with no extreme favorites (must be -130 as the biggest allowed favorite), and if you win 7 or more out of 10 you get your winnings and an extra free bet of $56.
I think the EV of 1 is probably only slightly positive with big variance, so I'm not sure if I'll be doing it.
I'll definitely be doing number 2 because it is probably a very small +EV bet, and also I'll love paying attention to the mess I'll have created.
I'm guessing betMGM, DraftKings, and FanDuel will have opportunities as the game gets closer.

I’m not good at this internet thing, but maybe 2% of NFL games have a successful onside kick? I see nothing about this matchup that would make an onside success more likely than average.

That sounds a little high "as stated"; I don't think there is an average of one successful onside kick every 3 weeks (48 games) of the regular season. Did you mean that 2% of the attempts are successful? Or maybe that 2% of all games have any onside kicks at all?
I am just thinking of when the Saints pulled off a surprise onside kick to start the second half against the Colts in 2010.

Didn't the Ravens do that too, against SF, in 2013?
In other news, I just returned from the Suncoast and Rampart with prop sheets. Here, for now, is the Super Bowl 56 South Point/Rampart proposition bets (20 page PDF).

There’s no need to assume a Poisson distribution if you have medians. Median is what you are trying to get to with Poisson.

Will the private message betting window be open? 🤪
I’m gonna be looking at most of the same bets as last year:
Safety
Overtime
Scoreless quarter
Missed extra point
Successful 2pt conversion
Special teams / defense TD
Scoragami
FYI: Here’s last year’s discussion about Scoragami

Try to pick the props that are close to -130 to maximize the chance of getting the "$56 free bet".
I get about a 25%^^^ chance for 7 (or more) winners out of 10 doing it this way.
^^^: To work this out, I assumed that for their prop markets, if they offer -130 on one side, then the other side would be about +110.
Like you thought, very small +EV (assuming that the lines for each prop are -130 / +110 or close to that ).

Extra Info:
FYI: If you pick -110 / -110 ("50 / 50") props in every game, then the chance of getting 7 (or more) winners is closer to 17.2%.

That’s been my plan. They have a different bet that if I do a 4 team parlay and you get 3 of 4 you get a free bet equal to what you bet as a consolation prize. It has to be 4 bets no stronger a favorite than -200. I’ve been picking the 4 college basketball favorites closest to -200. Last night I hit all 4 at around +550. On the others were 2/4…..

Pretty good.
When betting on -200 teams (assuming each leg has a "bookmaker's percentage" of ~105%) the overall play is +EV, as long as the EV of the bet you have with the bonus is greater than about "47.5% x the free bet".
---
(Update: about 1pm, Pac time): Since it is fairly hard to get -200 for every team, if we assume that the average odds you receive are -150 per team, then the the EV of the bet you have with the bonus needs to be greater than about "55.5% x the free bet" , for the play to have a +EV overall.

***: I would like to win up to $2000 @ -500 on the "no side" of the bet (in other words I would like to risk up to $10000 to win $2000)
Note: I am happy with the odds of -500, so if you manage to find odds better than that at a different book, you can bet with them and keep the difference.
If interested, PM me for more info.

Here are the odds I am happy to offer on the Yes^^^:

Safety: Yes +1200
Overtime: Yes +1250
Any Scoreless quarter: Yes +375
Missed extra point: Yes +320
Will There Be a Missed Field Goal and / or / Extra Point: Yes +125
Successful 2pt conversion: Yes +300
Special teams / defense TD: Yes +260
Scoragami ( Scorigami ): Yes +2000 ***
***: I couldn't find a book that is offering this, so this is just a guess of what I think it should be (this offer is open to negotiation, for all other props on offer, the odds are non-negotiable###).
###: The reason for this is. IMO all the other odds are "fair odds" when compared to what was being offered with the sports books that I had access to, at the time I posted these odds.
----
"Extra stuff":
Not looking for huge bets, this is just for a bit of fun, so the maximum amount per prop that I am willing to accept is: $250 (your stake) or "to lose $1000" (my liability), whichever amount is less for each prop you want to bet on.

I bet that last year and cashed, and it's cashed the past 7/8 years. Apparently former Kicker Pat Macafee said they use a special ball for the opening kick. It's rock hard and it's very difficult to kick it out of the end zone. It's not a normal ball that has been conditioned for the kickers. In other words, not kicker friendly. Plus the returner is probably all jacked up and will want to return it if he has an opportunity to field it.

They have 30-cent lines on props, much like the Station casinos. The Rampart/South Point of 20-cent lines. I think William Hill is at 20-cents too.

You can only be sure a 20-cent line is better than a 30-cent line if the implied probabilities are very close to 50/50.
For instance
+350 / -450 is a vig of 3.88%
+150 / -180 is a vig of 4.11%
+105 / -125 is a vig of 4.34%

LV @ Cin

Pho @ LA

finally, according to Pro Football Reference, in 2021 the following were the touchback rates:
LA
season: 63.7% of kickoffs were touchbacks
playoffs: 11 of 18 (61.1%)
Cincinnati
season: 58.9%
playoffs: 12 of 19 (63.1%)
What does this say? In my small sample size, it appears that the opening kickoff in playoff games, seem to be touchbacks at a much higher rate than kickoffs in general.
Thoughts?

I certainly have found it to be true that the lower the implied probabilities of the event are, the wider this goes. If a game is thought to be an even match up it might even be -110/-110 . So your claim is interesting but would not be intuitive until experiencing it ... how do you come up with implied vig?Quote: Ace2You can only be sure a 20-cent line is better than a 30-cent line if the implied probabilities are very close to 50/50.

first TB kick - out of bounds, penalty
LV @ Cin
opening Cin kick - touchback
first LV kick - returned
Pho @ LA
opening LA kick - touchback
first Pho kick - touchback
finally, according to Pro Football Reference, in 2021 the following were the touchback rates:
LA
season: 63.7% of kickoffs were touchbacks
playoffs: 11 of 18 (61.1%)
Cincinnati
season: 58.9%
playoffs: 12 of 19 (63.1%)
What does this say? In my small sample size, it appears that the opening kickoff in playoff games, seem to be touchbacks at a much higher rate than kickoffs in general.
Thoughts?

I'm lazy and won't do the work... but I'll put out some thoughts..... In a cushy windless indoor stadium I think every NFL kicker can get a touchback over 80% of the time if that is the strategy the special teams coach wants them to use. In a wind driven snow slicked outdoor stadium (do I live in Buffalo?) it will be extremely difficult to get a touchback into the wind, and not a guarantee down wind, either.
Also remember the strategy part. Some teams (like the Bills{I think}) intentionally kick off shorter to try and pin the other team short of the 20 yard line, as the touchback gives the receiving team the ball at the 25 yard line. It's a risk/reward decision.
I expect these two teams to go for the touchback. I will be betting on touchback. As a reminder, if this is considered an even money bet, i tend to be correct 49% of the time....

btw you are getting a different answer from a vig calculator I foundQuote: odiousgambitI certainly have found it to be true that the lower the implied probabilities of the event are, the wider this goes. If a game is thought to be an even match up it might even be -110/-110 . So your claim is interesting but would not be intuitive until experiencing it ... how do you come up with implied vig?Quote: Ace2You can only be sure a 20-cent line is better than a 30-cent line if the implied probabilities are very close to 50/50.
For instance
+350 / -450 is a vig of 3.88%
+150 / -180 is a vig of 4.11%
+105 / -125 is a vig of 4.34%

link to original post
+350 / -450 is a vig of 4.04 instead of 3.88%
+150 / -180 is a vig of 4.29 instead of 4.11%
+105 / -125 is a vig of 4.34% with the calc. too
however your point holds up: greater "spread" as you go "up", that is move away from 50-50 even money probability, is needed to maintain vig. I'm using quotes since my terminology may not be standard.
6.24% vig for the Boyd line per calculatorQuote: WizardGood point. I checked the prop sheets and Stations breaks to above 30-cent at lines of +145/-180. Meanwhile, I saw a pair of Boyd lines at +120/-155. That, is quite stingy and gets the Wizard finger wagging of shame.Quote: Ace2You can only be sure a 20-cent line is better than a 30-cent line if the implied probabilities are very close to 50/50.

Let’s say the bookmaker holds 4% of all money wagered. If $100 of wagers come in at $55 on Team A and $45 on B, he’ll payout $96 for $55 if A wins and $96 for $45 if B wins, which in American format is listed as -134 and +113 (rounded, and they might quote at -135 / + 115Quote: odiousgambitI certainly have found it to be true that the lower the implied probabilities of the event are, the wider this goes.

Starting from the lines, you work backwards to get to the vig and implied probabilities. 134/234 + 100/213 = 100/96, the reciprocal of which is 96% = the bookmakers payout ratio. The fair line is (213/100) * 1/.96 - 1 = +122/122. (100 / (100 + 122) = 45% = the amount wagered on the underdog with 1 - .45 = 55% on the favorite. No rounding on these calculations
Now if the money came in at $75 A on and $25 on B, the lines would be -357 / +284 using the same method and payout ratio. The spread is much larger since, for the line on the favorite, the bookmaker starts with $75/$25 then takes $4 out the denominator to get $75/$21, which has a large effect on the fair line of -300
These are textbook examples and, in practice, the money lines are often moving as bets come in and A/B ratios change

Both the vig calculator you found and Ace are using the same formula. However, the vig calculator you found is rounding the overround components to 3 decimal places. Ace is rounding to at least 6.Quote: odiousgambitbtw you are getting a different answer from a vig calculator I foundQuote: odiousgambitI certainly have found it to be true that the lower the implied probabilities of the event are, the wider this goes.

I quoted the wrong post in one of my previous posts, which lead to some confusion, for which I apologize.
I'm trying to say that not all 20-cent lines are equal. Some places separate to 25 cents earlier than others. For example, I saw a pair of Boyd lines at +120/-155, which is quite stingy. However, I now see that Boyd has 20-cent lines on some props and 30-cent on others. As an example:
#121 Over/under 22.5 total points by Bengals -115/-115
#115 Over/under 13.5 total points in first half scored by Rams -110/-110
By the way, I also have a house edge calculate for sports betting.

Another thing to remember when looking at moneylines is that the fair line will always be closer to the underdog line. In a near 50/50 matchup, the fair line isn’t that far off the midpoint of the two, but in a very lopsided matchup the fair line is much closer to the underdog line. That doesn’t mean the vig is higher on the favorite…it’s just due to the math for lines expressed in American format
I think American format is the best for expressing betting ratios. For example, if a line is -130 it’s easy to see you’re wagering $130 against $100, or any amount at a 13:10 ratio. In European/decimal format this bet is expressed at 1.769, which isn’t as easy to interpret IMO. However, decimal odds are better for calculations. For instance, the implied probability of any wager, favorite or underdog, is simply the reciprocal of the quote (1 / 1.769)
Sort of like the metric vs imperial system. Without a doubt, the all-decimal metric system is better for calculations. But the imperial system can be better for everyday use, like if you want to roughly measure the length a room with your feet

I think I know what may have happened for the "350 / -450" and "+150 / -180" figures, as 3.88%^^^ and 4.11% *** are the correct "implied house edges" for those examples.
^^^: 1/ ~1.0404 = ~ 0.9612 = ~96.12% RTP = ~3.88% house edge (edit: about 525 pm, Pac time)
***: 1/ ~1.0429 = ~ 0.9589 = ~95.89% RTP = ~4.11% house edge (edit: about 525 pm, Pac time)
Also, I know it isn't much of a difference in the above examples, but it can make a fairly big difference the further away you get from 100% expected RTP.

OK...I find this interesting.
I cannot find this exact bet on FD, that said at FD...
"To score every quarter:"
Cin-No -340
LA-No -200
It seems to me, if I put down $100 at Stations, I'd win $20
If I put $50 on each side at FD, I'd win $39.71 if both hit, and lose much less if one side hit.
Am I looking at this correctly?

-500 is the yes, not the no.

They use a different ball for SB kick offs vs playoffs. Last 26 of 28 SB have resulted in a return. And one of the kickers was Justin Tucker who managed a touchback. Strongest leg in the league. It’s a commemorative ball, it’s like kicking a rock according to a kicker who has kicked off in the SB. Eventually this prop is going to become minus money,, last year was almost plus 300!

That would be stunning if a ball with different characteristics for kicking in the Super Bowl than a regular season game or playoff game was used! I've already plunked down money at -130 on YES TOUCHBACK. Hope you are wrong!
So I had to pick exactly 10 props, $10 each, no favorite more than -130, and if I win 7 I get a bonus free bet of $56. I decided to try and get correlated picks, so I am more likely to be 7+ out of ten if Rams do well, but likely to be 3- out of ten if the Bengals do well.
Here they are. They range in odds from -105 to -130.
Rams first team in red zone
Rams have last possession of the game
Bengals punt 1st
Longest score is a FG (I am not sure if a FG is kicked from the 30 yard line if it is counted as a 40 yard score or a 30 yard score)
Rams first team to throw TD pass
Rams longest scoring drive
Rams more offensive plays
Game NOT tied again after 0-0
Rams most FGs
Rams longest TD
Edit…. STUPID pick! Rams most FGs . If it ties does not count as a win towards 7 wins. Oh well. Live and learn.
