ND has a talent issue. I think the gameplan wasn't strong (keep 7 in the box on D; get the ball to Eifert at any cost), but they adjusted on offense and had success. They tried to adjust on D with run blitzes and bringing a safety up, but their defensive woes were lack of athletic ability and quality depth. They didn't stumble into being 12-0; they just never faced a team as athletic as ours (USC doesn't count when the coach wastes the talent and OU has been notoriously soft recently). It's taken UT a while to recover because they never had that elite QB again; those spread read-option offenses require an elite QB (Tebow, Cam, Johnny Football, Vince, Colt McCoy). I think ND has a better coach than UT. On a side note, it's scary to think what CNS could do at a place with built in recruiting and the resources of UT or USC; we have the financial resources, but we have to recruit out of state well to get a top class.
