I think Iowa can get by this week with just wegher and paki. The strength of IU's defense is their defensive line. They are a very strong group, very similar to iowa's group. IU's defense is horrible in the secondary. They are not very good and if Iowa can dink & dunk it down the field on short passes, they can get by IU.
It will be interesting to see what the coaches do, I would keep an eye for where they line up some of the guys. I bet we see a lot more screens this week, because IU front 4 and their LB's like to blitz and get up field. Possibly the jail break screen and some TE's screens.
I just don't think Wegher will carry the ball more than 15 times and if he gets hit hard in the ribs, he could be done.
