Every state has lotteries. Our kids are brought up with it. I'm sure some gambling goes on at all colleges. Athletes have to be especially careful because it's against NCAA rules and could affect their eligibility. They have to think through the consequences.
Every team has at least a couple of gamblers.
The easiest place on campus to find a bookie is a practice. It won't take long to find someone on a team who knows how to get a bet down with a bookie. The plate is pretty full with issues. Alcohol, drugs, now gambling. It's quite a bill of fare.
