Iowa St and Tech both return very good QBs. ISU also returns a good defense.Our season hinges mostly on Sam's health. He hasn't stayed healthy either of the last 2 seasons for the full. He's gotta save himself for the big games. With WVU and OSU starting new QBs, those are 2 losses we should erase. We're never going to get an easier path to the Big 12 with everyone except Baylor with a new QB.
I also consider OU as having a returning starter.
