IOWA CITY, Iowa -- Halftime analysis from Kinnick Stadium, where No. 12 Iowa leads Michigan 20-14.
Turning point: Trailing 14-13, Iowa faced third-and-24 from its own 45-yard line when Ricky Stanzi found a diving Derrell Johnson-Koulianos for a 47-yard gain. The pass set up Brandon Wegher's go-ahead touchdown run.
Stat of the half: Iowa finished with 204 first-half yards, 201 of them through the air. The Hawkeyes have been fairly balanced on run-pass attempts (18-21) but generated very little on the ground despite having the lead.
What Michigan has to do: Hold onto the football. Turnovers have absolutely killed Michigan in this game, wiping away a decent performance from the offense. Running back Brandon Minor is showing what he can do when healthy, but he needs to hang onto the football. Same goes for quarterback Tate Forcier, whose good plays have been overshadowed by two turnovers. Michigan also has to tighten up in the secondary, which still allows too many big plays.
What Iowa has to do: Generate a run game. Stanzi can make plays against a vulnerable Wolverines secondary, but he also has a tendency to commit costly turnovers. The Hawkeyes need to spark their rushing attack and do a better job of containing Minor in the second half.
