This is the biggest question and has been for some time.
Here's my glass-half-full answer to that question: While still shooting ourselves in the foot too much, we seem to have overcome it better than in the past. Against Miami - a team that has talent but one we should have beaten without too much problem - we didn't play particularly well. We let them score first. We turned it over a couple times. The completed a much higher percentage than we usually allow and gained 359 yards through the air. But we still had the game well put away as it came down the stretch. In the past, those games have come right down to the final play.
Against MSU - a team that was at least as good as us and probably better - we looked to be headed toward a one-sided affair similar to tOSU or Wiscy II in 2012 or Wiscy in 2011. On the road, night game, highly-ranked opponent and we let them get out to a big lead. However, this time we kept fighting, made a run and had a chance to win at the end. Much better against a fairly evenly matched opponent than has happened often in the past.
We still need to be better. But it seems like we've handled a couple of those games better than we have in the past.
