Nebraska has good skill players on offense, the OL is just fing terrible. Nebraska hasnt had great oline recently, but this one is on another level of suck. Grant is a good RB, but would have like 3 guys right in his face before he even gets the ball.
Due to the OL, its tough for Nebraska to maintain drives, but Casey Thompson is a good QB, it only take 1 play for Trey Palmer to bust open, and Anthony Grant can make something happen here or there. So they can get into scoring position a few times per game.
The defense has been good enough for Nebraska to win games since Purdue. They just didnt have much help when Thompson was out. With Iowa's anemic offense, they should be fine there, I dont think Iowa will be able to consistently move the ball.
This should be a butt ugly game. Nebraska beat Rutgers 14-13 and lost to Wisconsin 14-15. I expect this game to be similar. Probably just comes down to turnovers and Iowa has the best unit on the field in their defense. If Nebraska had even an average OL I think they would win, but it is just god awful.
