Petersen is retired correct? Not saying he'd come here or that I'd want him as I'm all in on Urban as well, but unless you meant Petersen's dream job is retirement then he's not coaching anywhere that I know of.Urban's issue is he can't control his own program and has sometimes sacrificed character for performance in recruiting. But he certainly knows how to take a program and turn it around, quickly.
Peterson wouldn't take the Texas job. He's a homer to the Pac NW and is sitting in his dream job. I wouldn't want him simply because he doesn't really want to be here.
There are one or two I would consider rolling the dice for after Urban. The list is short though.
