Birm, you believe the CBs and Safeties will be a bright spot for this year's defense and they will have quite a few take-aways. Does that mean they have learned to turn their heads to track the ball? And won't just cover with their backs to the QBs, which often draws pass interference penalties.
For the team to be successful, the defense needs to be elite, especially against ND, Penn State, Wisconsin and Michigan. The defense needs to win four regular season games, and then excel in the playoffs.
Remember the Northwestern game? 40 mph winds. Then there could be a game in rain and/or snow!
