I thought the offense was the problem as well, at least early on, but then it got a lot better down the stretch (once Kill was out of the picture). I think Limegrover proved he belonged, but I support the change regarless.
The defense dropped the ball last year, and I know there were injuries, but the depth and ability to adapt was not there as expected.
The performance by the Defense in the Wisconsin game was very troubling to me. Wisconsin had a very beatable team last year, and Stave threw the pick to start the game down 7, and Wisconsin could have collapsed in a rout. Of course that did not happen. The rest of the game was awful as the Freshman laden O Line and third tier Wisconsin RBs ran the ball down our throat, play after play, series after series. That was the worst game of the year, even worse than Kent State and Northwestern.
I thought the defensive coaching, long considered a strength, really was exposed in the Wisconsin game. If the team was so injured on the DL (and they were), some radical in game adjustments, or personnel changes early in the week might have helped. I was never as pissed in recent years as I was in the first half of the Wisconsin game last year. If Minnesota could not manage to beat Wisconsin this year, /(or hold a 17-3 lead while making Alex Erickson look like Jerry Rice in 2014) I am starting to question if Minnesota will ever beat UW again in football.
