The Big Ten is an embarrassment. After OSU's meltdowns against LSU and Florida in the 2006-07 Championship games, there was this knee-jerk reaction by the conference at large to go spread. I'm not sure if we're all having growing pains in the middle of that process, but the talent disparity is sickening.
I.e., Nebraska lost by 6 last night, but one who would watch that game without knowing the score would have just thought UCLA was thrashing them. Fact is, talent is less in the B1G, speed is less in the B1G. Only Michigan and OSU have every consistently competed nationally relying on talent. For everyone else, the 1990s Wisconsin teams provide the best model for competing with the Pac-12 and SEC (massive O-line and dominant D-line; see 1999 Rose Bowl win vs. UCLA). Iowa used this equation well in the 2000s, and accordingly, we held our own against the SEC and Pac-12.
If you win in the trenches, and have a powerful rush game, you can stay in it and physically match them. The B1G has always been a step slower, but now we're slower and undersized.
