I think ti is a bigger problem that most would think. The online card games and other things start it then players get relaxed about it. I would think every college coach would be talking to their players this week about it. Reminding them what they can and can't do and to stay away from anything iffy. I don't think college players realize what they can and can't do.
NCAA rules prohibit athletes, coaches and staff from betting on amateur, collegiate and professional sports in which the NCAA conducts a championship. For example, athletes cannot bet on NFL games even if state laws would legally allow them to if they weren't competing under NCAA rules.
