MADISON, Wis. -- Instant analysis from halftime at Camp Randall Stadium, where Wisconsin leads Iowa 10-3.
Turning point: After a miscue by punt returner David Gilreath pinned Wisconsin deep, the Badgers pounded away at Iowa's defense on an 11-play, 92-yard scoring drive that took 4:59. Running backs John Clay and Montee Ball both found openings, and quarterback Scott Tolzien completed 4 of 5 pass attempts, using play-action very well.
Best player in the half: Clay has exhibited both power and patience for Wisconsin, gaining 69 yards on 14 carries. He could end up wearing down the Hawkeyes after halftime. Honorable mentions go to Badgers defensive end O'Brien Schofield (2 TFLs) and Iowa defensive end Adrian Clayborn (sack, 2 TFLs).
What Iowa needs to do: Attack Wisconsin down the field with its wide receivers and tight end Tony Moeaki, who has been a nonfactor. Ricky Stanzi hit Derrell Johnson-Koulianos for a 34-yard gain, setting up Iowa's only score. There are openings in the deep middle, and the Iowa run game is going nowhere. The Hawkeyes also need to be durable against Clay.
What Wisconsin needs to do: Keep pounding away with Clay but don't abandon the play-action pass, which has been valuable. The game plan has worked well so far, but the Badgers can't afford major mistakes like they had last week.
