– A week filled with upsets likely will cause a major shake-up when the Associated Press Top 25 is released Monday.

One beneficiary should be Iowa, which is back atop the Big Ten after yet another impressive victory.

Jarrod Uthoff scored 23 points and the 16th-ranked Hawkeyes beat Michigan 82-71 on Sunday for their first 5-0 start in the Big Ten in 19 years.

Peter Jok had 14 of his 16 points in the second half for surging Iowa (14-3), which could be poised to push for its highest ranking since cracking the top 10 two years ago.

"The key is to keep coming down and giving your team a chance," coach Fran McCaffery said. "I thought our shot selection was really good, and we hit some key shots."

Iowa, which has won seven in a row, scored the game's first 11 points, then broke open a tight game with a 16-3 run midway through the second half. Jok then buried a three-pointer that made it 76-68 with 2 minutes, 34 seconds left.

Derrick Walton Jr. scored 16 points for Michigan (13-5, 3-2 Big Ten). The Wolverines played their fourth game in a row without star Caris LeVert, out because of a left leg injury.

"What is really separating them right now is the bench play," Michigan coach John Beilein said of the Hawkeyes, who got 22 points from reserves. "They were the better team than us without question. We fought hard."

Iowa's 76-59 blowout victory at No. 4 Michigan State earlier in the week further cemented the Hawkeyes' status as a legitimate Big Ten contender.

Iowa avoided a letdown against the Wolverines — who were coming off a 70-67 upset of No. 3 Maryland — and joined Indiana atop the league at 5-0.
