This is definitely an issue the NCAA is going to have to address... a few years ago over 25% of NCAA football players admitted to using it, and I can almost guarantee that number has risen. Evander Holyfield's son is a football player at Georgia and he just got caught less than a month ago. It is so widely accepted as "ok" that kids have a tough time when it is cut out.
The Univesity of Nebraska does a pretty good job of telling RAs or any other supervisors if an athlete is in trouble they need to for the most part contact an athletic department representative first (depending on severity of course). That being said, if someone else complains or discovers it first, it puts the RAs and police in a tough spot. If they confirm the report, for the most part someone has to be ticketed. Nebraska also has an extensive list of former policemen, players, and faculty, that at the drop of the hat will pick an athlete up from anywhere if he's had too much to drink and it's why DUIs are really tough for me to understand.
But Keyshawn is starting his freshman year off on the wrong foot, and now he's flagged by the NCAA. We will find out in the next couple years if he truly has a problem because he will get tested, a lot.
