Michigan’s Jim Harbaugh Previews Iowa

Michigan coach Jim Harbaugh says Iowa’s style of defense dates back to the early 80s when Phil Parker played for Norm Parker at Michigan State.

The fourth ranked ranked Wolverines look to stay unbeaten on Saturday with a visit to Kinnick Stadium.

Harbaugh says the key against the Iowa defense is to limit mistakes.

The Hawkeye defense faces huge challenge this week from running back Blake Corum, who averages more than seven yards a carry and has scored nine touchdowns. Harbaugh says Corum’s biggest strength is his ability to make defenders miss.
