Michigan has flipped Iowa commitment Ben VanSumeren, a three-star fullback/tight end. The 6-foot-3-inch, 228-pounder from Essexville Garber High in Essexville, Mich., was offered by the Wolverines three days ago. VanSumeren had committed to the Hawkeyes on Nov. 10 and expected to sign during the early signing period, which begins Wednesday. He made the announcement Sunday on Twitter. VanSumeren thanked Iowa coach Kirk Ferentz and his staff and wished the program well.
