While it's true MSU had a better season last year than Nebraska has managed since probably 2001, they are also the same program that since 2006 has gone 4-8, 7-6, 9-4, 6-7, 11-2, 11-3, 7-6 and 12-1.
Certainly several impressive seasons, but they haven't been the model of consistency since Dantonio took over. And, since he did (Nov. of 2006) they've had two 7 win seasons and a 6 win season.
This is always an interesting topic for debate, though - if you look at that record for MSU since 2006, would you take that? Would you take a Rose Bowl win and conference title in exchange for three very poor seasons in the same time frame? Or, would you prefer consistency in the form of #9wins and a few conference title trips, but, no trophies?
