PT to Colorado would be a mistake. He has to know that.
Perfect move would be to a G5 school in the east / southeast. Something along the lines of Marshall, Troy, UCF, USF, that level. Go there...recruit well...win 10 games...and now you're set up for the leap to P5.
Cincinatti? Yeah, but does he really want to step into the shadow of Fickell? PT's at his best when he's casting shade, not walking in to it.
One more year at Jackson State. Enjoy coaching your son. There's a right fit for him out there, but neither of the UC's are it. JMO.
Go Vols.
