That's not getting fixed in a bye week. OSU should have lost the Arkansas game, and their QB situation is a mess, which Gundy really hasn't had a problem of his entire time at OSU. Bowman has been awful and Rangel is a poor passer and hasn't been the QB that they hoped he would be. I guarantee you that Gundy did not want Bowman back, he wanted Rangel to step up and become the starter and that hasn't happened at all. So this is an issue that Gundy hasn't had to deal with much at all.
With that said OSU has a boat load of talent at WR and RB... just nobody to lead it on the field. And defensively I think they are down their best defensively player and their DL is really bad.
