I'm assuming he got wind that Sark was USC's first choice so he withdrew. Just not sure what's the allure of Washington. Seems like, if Peterson was a serious candidate for USC, that he'd be a serious candidate for somewhere better than Washington in the near future. Maybe he won't mind jumping after a year or two but it seems like that would hurt recruiting down the road. Once a coach gets the rep as a job-jumper, the kids know that it's unlikely he'll be around for their 4-5 years.
