with manny out, 1/2 our db's will be new or will little game experience. we were vulnerable prior to manny's suspension. if our dt's can't clog the middle and our de's get a rush, they could control the los when they have the ball. if allen really is as good as the hype, and if this turns into a game of catch up, for Iowa, we could lose. we have no evidence on how our offense will perform, outside of the running game. but you generally don't come from behind by running the ball.
I still think this game could go either way. Iowa should win because they're at home. But, this game isn't a gimme.
