There's only a few hours left on this Friday, but there's still time for the four factors.
Get early pressure
In each game this year the Iowa defense has come out and stayed in its base 4-3 for the opponents entire (if not entire, close enough) first drive, and the past 3 weeks those drives have ended in the opponent scoring. To Iowa's credit, they have made great halftime adjustments and have played excellend second half defense. But Iowa needs to make adjustments quicker on defense to avoid faling in a big hole like last week against CMU.
So how to do that? It starts with pressure on the quarterback. A lot of the second half adjustments have been finding ways to help the struggling defensive line get in the backfield. It would be great if Iowa didn't have to send in blitzers, but after a month of football, we've seen that they do. So don't wait until the second half to mix it up on D.
The good news for Iowa is that MarQueis Gray suffered a high ankle sprain a couple weeks ago and will likely not play and definitely not start. So in his place is the much less mobile Max Shortell. He's got a good arm and can move around in the pocket a little, but isn't going to be as big of a threat to run a sweep on 4th-and-goal from the 2 in the final minute of the game and score a game-winning TD.
