EAST LANSING, Mich. (AP) — Less than a month ago, Iowa was coming off a startling loss to Central Michigan. The Hawkeyes didn’t look like a championship team in the MAC, much less the Big Ten. Then the conference season started, and the turnaround was immediate. After Saturday’s victory at Michigan State, Iowa is tied with Michigan atop the Legends Division heading into next weekend’s big home game against Penn State. Mark Weisman ran for 116 yards and the tying touchdown Saturday before hurting his right ankle. He’s been instrumental in Iowa’s improvement, averaging 6.3 yards per carry with eight rushing TDs on the season.
