Except you throw tendencies out when the WRs cannot catch anything. At some point you realize the only thing that's worked is the Wildcat and Homer getting yards out of a spread look. Just do what works until it doesn't.
Oregon actually had some pretty good OL. OL wasn't the problem. Helfrich's DC retired, Kelly never recruited a QB, Helfrich found a 3 star named Herbert to be his new QB, but got fired before he had a chance to develop Herbert.
Is this the biggest year to year change you have ever seen in a team? I know we got lucky and stole a few, but we generally appeared like a prepared team. This year it doesn't look like we have even practiced.
