I havea high school buddy who is a BYU Grad, and got a degree in sports medicine. He interned with the Dallas Cowboys. He said it was absolutely crazy. Players watching porn--all the time. Players hooking up with random chicks, and trying to get him in on the action. Women throwing themselves at all things Cowboys. Hard partying and drinking. And some of these dues were married, although most were single. Said he hard to say no to booze fests, wild women and other crazy stuff on virtually a daily basis because guys wanted to involved all people on the team, or associated with it. And this was 13-14 years ago, so I imagine it is worse now than then.
Yeah, the $$$ would be sweet. And yeah it would be cool to play a sport. But I think it would be really tough for a single guy in the wrong locker room. Much easier to avoid stuff as a married man. Most BYU guys in the NFL are married, and that has to help them avoid the nonsense.
For what it is worth....
