Warren's pick-six gives Michigan quick lead

Posted by ESPN.com's Adam Rittenberg

IOWA CITY, Iowa -- Iowa head coach Kirk Ferentz has defended quarterback Ricky Stanzi multiple times this season, and he'll likely have to do so again.

Stanzi and wide receiver Paul Chaney Jr. appeared to have a miscommunication on a short route, and the result proved disastrous for the Hawkeyes. Michigan got the start it wanted, as star cornerback Donovan Warren picked off a Stanzi pass thrown nowhere near a receiver and raced 40 yards untouched to the end zone.

Stanzi has now thrown pick-sixes in consecutive games. He has as many interceptions as touchdown passes (8) on the season.

As strong as Iowa's defense has been, no team can repeatedly survive major mistakes from its starting quarterback. Just as Wisconsin after today's loss to Ohio State.
