Their credibility has never been what you would call good but this year, especially with these two examples you have given Roy, they have been nothing short of side humor and that's it.
Let's not forget that they knew for years that USC and Reggie Bush was dirty and never did any type of in depth investigation there but after Pete Carroll leaves and Reggie is an established Super Bowl winning star in the NFL, let's sanction the school.
When are they going to learn that one of two things have to occur to clean up collegiate sports
1.) Give the athletes double value scholarships with the extra value being cash in their hands.
or
2.) Sanction the coaches and players from years of participation in collegiate sports.
If a program is dirty and its the coach, and let's face it, it usually is the coach, suspend the coach for two years from college coaching. If a player is caught to be dirty suspend him for an entire year.
This is just a start but there can be a load more added on.
