Glenn Robinson III scored 20 points and pulled down 10 rebounds to lead No. 2 Michigan in a 95-67 rout of Iowa on Sunday.
Trey Burke had 19 points and 12 assists, while Tim Hardaway Jr. added 19 points, five rebounds and five assists for the Wolverines (15-0, 2-0 Big Ten), who stay undefeated on the season after their eighth straight double-digit victory.
Roy Devyn Marble scored 14 points and Anthony Clemmons gave 12 points and seven helpers for the Hawkeyes (11-4, 0-2), who were coming off a 4-point loss to No. 5 Indiana on New Year's Eve to begin conference play.
Iowa scored the first seven points of the game and still led past the halfway stage of the first half, with Mike Gesell draining a 3-pointer and Melsahn Basabe following with a dunk a minute later for a 21-17 advantage.
Michigan, though, ripped off a 9-2 run capped by a Hardaway 3-pointer that gave the team a 26-23 lead with 4:28 left in the half. Marble was fouled as he hit a 3-pointer on the following possession and made the foul shot, but Burke countered with a 3-ball of his own for a 29-27 Wolverines' edge.
The Wolverines led by just three, 38-35, after Aaron White hit a jumper for Iowa with 1 1/2 minutes to play before intermission, but Michigan scored the final eight points of the half for a 46-35 lead after 20 minutes.
"We've been in a lot of games where 15 minutes into the first half, we might have had a double-digit lead," Michigan coach John Beilein said. "We didn't have that today. We closed well, and then we came out in the second half and really played good from the get-go."
Michigan got a 3-ball from Hardaway to start the second half, and later used an 11-2 run to push the advantage to 64-42 on a Burke jumper with 12 1/2 minutes to play.
The Wolverines pushed their lead to as high as 35 in an easy finish to the contest.
"I told them we needed to be tougher," Iowa coach Fran McCaffery said after the game. "We can't play the No. 2 ranked team and not be as tough for 40 minutes. We were tough for the first 15 and were tough, at times, in the second half, but it's having the mentality we're going to stay after it until we get the decision."
