The visible sense of entitlement which is manifesting itself in a lack of effort and quitting in the middle of games is already a big problem when your entire team is mercenary and can leave at any time. I keep bringing up the Clemson/Penn State bowl game a couple of days ago where it could not have been clearer that neither team cared at all about the game. I think these athletes forget that they are entertainers, and are getting paid to entertain. And I also think that a 20 year old suddenly getting $100,000+ a year is going to have trouble adjusting and dealing with the implications of that.
