Well, Wisconsin may have lost two DL starters in this game. If both those guys are done for the year, this team doesn't win the B10 west. You can't lose your front seven, then lose two of your new starters, and just replace them and perform the same. That would mean you would be starting your 7-8-9 best starters from last year. Our DL would be McMInn, Meier, bazata, and a RS Freshman tackle.
Wisconsin may be deeper than Iowa on the DL (honestly, with what we have, i doubt that), but you just can't win the B10 with guys that aren't ready. LSU went to the power game when the warren got hurt...and Wisconsin didn't have an answer.
