Nobody is immune from players gambling. Realistically, I’d be surprised if any team is clean on this.
And it’s not new. In Tuscaloosa in the late 70s, I had a friend whose roommate was a player you would recognize. The player gambled a lot, and not just on football. Don’t know if he bet on Alabama games, but it wouldn’t surprise me.
Reason I mentioned coaches earlier. As you stated, no one is immune. I’m aware of several former coaches involved heavily in a variety of gambling activities, from sports to high stakes poker. And I was told at least a couple “weren’t very good at it, and one in particular had lost millions”. And the person relaying this to me would know as he is very well connected in the gaming industry.
Like these student athletes in Iowa, the activity is being funneled through third party accounts. But word gets out eventually.
Were these coaches gambling (to this extent) while actively in coaching? I can’t say. I’ll just say I’m extremely skeptical that they suddenly “jumped in both feet” after leaving the game.
I use to be one of those that believed that gambling influencing the outcomes of games was mostly built on conspiracy. But as it has more pervasive and common place, I can see the door of opportunity opening.
