Arizona self-penalized as a token gesture in the face of some serious allegations from the NCAA. Five Level-1 violations is just huge, and while I've come to accept the NCAA as a spineless organization that won't enforce its own rules** I wouldn't be surprised to see Arizona get another year or even two and lose scholarships on top of their self-imposed ban.
**It is very ironic that I despise the NCAA for not enforcing its own rules, because I think its rules are horse-pucky and that whole thing should be re-thought from the ground up. But if the NCAA is going to insist on its stupid rules, it needs to enforce them.
