@Grey Wolf
Instead of any of the actions I expected him to take, he barely tried to push back, didn't try very hard to figure out why the Oklahoma staff was acting the way they were, or anything else. Instead of any of that, he was out of there like a shot and off to USC, where he had the agreement that he needed but where the coaching staff has repeatedly screwed with him in other serious ways - and he's largely (not entirely, but largely) shrugged them off.
I think you make some good points, Grey Wolf. However, at Oklahoma time was a factor. His commitments to promote several movies were imminent. Also, his lawyers didn't want him making waves with the NCAA after their recent settlement. The MC didn't have Time to resolve the issues, and they would immediately effect his rights, and cause him to have to break some commitments.
However, since Oklahoma was renegging on the contract, he could get out and retain his eligibility, but only if he acted right away.
USC he knew his rival already had a year in the program, and was favored by the head coach. He accepted possibly playing defense, with a year long plan to replace the planned #1 QB.
So, he has time to plan, bring in supporting players, and "groom" them similar to what he did in high school.
The two main differences between Oklahoma and USC, 1): Time. 2): Oklahoma Broke their Word.
USC's head coach is a jerk. However, he is keeping his promise to his #1 QB. He has been a bit sketchy about the scholarship (that he doesn't need, its principal); however, the head coach has not lied (yet). He is arrogant, and mistaken, etc.
