The NCAA itself needs investigation...for a ton of things. The pile of corruption has been mounting in all kinds of ways. The BCS system is a crok. You have Bowl administrators making 400k a year. Favoriti$m runs rampant.
And the notion that Cam's father is culpable but his son is not is such BS. The NCAA and ESPN machine has fated Cam for the championship game and heisman award.* They won't let this little scandal get in the way.
If you want to see an interesting parallel take a look over the past decade at how many times:
1. Schools without big money from conferences without big money play for a title. (Answer: never)
2. How often teams that play in the title game happen to have the Heisman player on their team. (Answer: almost every season) What a coincidence.
