The bottom line for OU is they lose almost everybody on offense, and practically nobody on defense. If Bradford leaves it would be 8 longtime starters gone off the offense including the entire offensive line. Off the top of my head the defense just loses Nic Harris and Lendy Holmes. Possibly Demarcus Granger if he foregoes his senior season and goes pro. Which is possible since he would be considered a first rounder or early second. OSU will be a veteran team next year and probably should be rated ahead of OU. But the only problem they may have is breaking in some new coaches. Losing DC Beckman to Toledo was huge.
Don't forget Mccoy on Defense. He'll be gone too
