When the dust settled on Iowa's 24-10 win against Wisconsin on Saturday, the numbers were clear. The Hawkeyes had held the Badgers to 51 rushing yards — just 1.6 per carry.
Chalk it up as another dominant performance for a Kirk Ferentz defense that has helped Iowa to three straight victories in a tight Big Ten West title race leading into Saturday's matchup with the Gophers.
The Hawkeyes have already faced three of the Big Ten's top four leading rushers in Illinois' Chase Brown, Michigan's Blake Corum and Wisconsin's Braelon Allen.
Now they'll have to face arguably the toughest runner to tackle in the country in the U's Mohamed Ibrahim, the Doak Walker Award running back of the week.
"Like all good players you have to defend him every play and defend him until the whistle blows," Ferentz said at his Tuesday news conference. "He's just a tough football player. Looks like there's nothing there and next thing you know he's got a five or eight-yard gain. So if you don't tackle or get him down, he's not quitting."
Ibrahim, who ran for 178 yards and three TDs in last week's 31-3 win against Northwestern, leads the second best rushing offense in the Big Ten with the Gophers averaging 221.1 yards, behind only Michigan's 251.4.
Iowa's defense has come a long way since giving up 27 points to Michigan and 54 points to Ohio State in blowout losses last month. The Hawkeyes have given up only 26 points combined in the last three games.
"We have enough guys at the top that have been really strong," Ferentz told reporters after beating Wisconsin. "I couldn't sign off on that three weeks ago, four weeks ago, but you bet on people, and you bet on people that you've been around and see how they respond."
