The passing game is working -- 6.1 YPA and 66% completion rate gets you twelve yards in three plays. That gets you a first down, and your drive continues.
The IOWA WAY of running is netting 2.9 YPC -- that gets you a punt. Greg Davis' horizontal passing as running game is working way, way better than the traditional zone read and power-o plays that Iowa kept in the offense from the pre-Davis era. I would venture a guess that Greg Davis has his hands tied WRT running the offense, just from watching the way the game is played. That back to back two minute drill against Ball State was all passing, and it is the only time this year the Iowa offense moved the ball consistently. The running game is killing the Hawks.
