I'm late to this comment and I see the awards so I know I'm in the minority, but I disagree. It's not their fault...but... These kids are under their tutelage. This is a message that shouldn't need to be pounded into their heads but maybe I'm wrong. The amounts don't matter. You can't bet on your own team or anything you have a relationship with rules or not. The rules say definitely not. Tell the kids once a month do not gamble and is probably doesn't happen. If it does... maybe you're not a great teacher.
I love Campbell and I don't think this is his fault. But to say zero responsibility... I don't agree with that. You're the leader. Lead.
How exactly do you think he should have dealt with this type of situation? As a leader, you educate as much as you can. I'm sure he and the athletic department speak often of gambling. When I was an athlete we got it pounded into our heads and that was before sports gambling was legal. When I was a college coach, we hammered the point especially around the start of big wagering events/seasons.
Campbell also educates through books and preaches good decision making.
These were student-athletes that aimed to deceive. They hid their identity. No amount of education would have directed them from the path they chose.
