I'm sure he's been told. But many of these guys never want to admit they've made a mistake. They become less of an "expert" if they do. Ever hear Colin Cowherd say he was wrong? Never to a listener, only when he's called out by an in-studio guest.
Cowherd is a buffoonish know it all.
Sal, like Simmons, at least pretends to be humble. I think he'd be willing to admit the error. Maybe he just thought it wouldn't be entertaining.
Only thing that kinda annoys me with those guys is they still play up the ordinary guy routine, even though they are now very wealthy.
It's all sort of weird to me. I don't totally get squares (who are not idiots) who insist on being square. But I do have friends like this, who bet on stuff like their assessment of the coaches, or their belief that one team will be really motivated. I explain to them why they are wrong, and tell them how to make money, and they ignore me.
I think part of that is just the dream of gambling. But I'm pretty confident that if these guys had millions in the bank, they'd promptly lose interest in trying to beat their bookies for $200 on Sundays.
