The Gophers football team is 4-0 heading into Iowa Week, just like last year, when the Hawkeyes took all that momentum and squashed it, sending Minnesota home with a 31-13 defeat.

“They physically got after us a year ago — physically, mentally, every phase of the game,” Gophers coach Jerry Kill recalled Sunday.

The Gophers hope this year’s first four games prepared them better, and there is some statistical evidence that they’ve improved, with the 3-1 Hawkeyes set to visit TCF Bank Stadium on Saturday.

“I think we’re a bigger, stronger team than we were a year ago, but so are they,” Kill said. “I think they’re a much better team than they were a year ago, without a doubt.”

The Hawkeyes finished 4-8 last season. This year, they rebounded from a season-opening loss to Northern Illinois with victories over Missouri State and Iowa State before throttling Western Michigan 59-3 on Saturday.

The Gophers defeated Iowa in 2010 and 2011 to claim the Floyd of Rosedale trophy, and to get it back, they’ll have to stop Mark Weisman, who had 155 yards by halftime last year. Minnesota also will have to limit turnovers, as Max Shortell had three interceptions and a fumble in last year’s defeat.

Shortell was subbing for injured MarQueis Gray, and now the Gophers have Mitch Leidner at quarterback, with Philip Nelson recovering from a strained hamstring.

All signs point toward Leidner starting against Iowa. Kill said Nelson’s hamstring injury is about 80 percent healed, adding that tailback Donnell Kirkwood’s sprained ankle is about 90 percent healed.

“You can’t sell out and play kids that are 85 percent,” Kill said. “Number one, it’ll get you beat. Right now, 100 percent of Mitch is better than 80 percent of Philip. One hundred percent of David Cobb is better than 90 percent of Donnell.

“If you’ve got 100 percent of Philip Nelson or 100 percent of Donnell, that’s a different deal.”

Last year’s loss to Iowa sent the Gophers to a 2-6 Big Ten finish, same as in Kill’s first season. Will Saturday be different? For some perspective, here’s a look at how the Gophers got to 4-0 last year and this year:

The opponents

2012: The Gophers defeated UNLV (in three overtimes), FCS New Hampshire, Western Michigan and Syracuse. Three came by seven or fewer points. The first three opponents were cupcakes, but Syracuse finished 8-5 and beat West Virginia in the Pinstripe Bowl.

2013: The victories have come against UNLV, New Mexico State, FCS Western Illinois, and San Jose State. The Gophers trailed Western Illinois 12-7 late in the third quarter, but they’ve pulled away to win each game by at least 17 points. The first three opponents were soft, but San Jose State was 11-2 last year and remains dangerous with elite quarterback David Fales.

The offense

2012: Thanks largely to a 44-point output against New Hampshire, the Gophers averaged 30 points per game, 184 rushing yards per game and 222 passing yards per game. They ran on 65 percent of their plays.

2013: They’ve averaged 42 points per game, rushing more effectively (282 yards per game) but not passing as well (105 yards per game). They’ve run on 76 percent of their plays.

“I think we’ll throw it more [moving forward],” Kill said. “We’ve just taken what the defenses have given us.”

The defense

2012: The 17-10 victory over Syracuse was the highlight, as the defensive line rattled current New York Giants quarterback Ryan Nassib with pressure. The Gophers allowed 17 points, 135 rushing yards and 180 passing yards per game.

2013: The Gophers have allowed 20 points per game. They haven’t defended the pass as well (allowing 270 yards per game), but they’ve been slightly better against the run (allowing 103 yards per game).

Other key categories

2012: The Gophers had a turnover margin of plus-5 through four games. But they were flagged for 31 penalties for 238 yards.

2013: The Gophers are plus-3 in the turnover margin and have committed only 10 penalties. They rank fourth nationally in fewest penalty yards per game, with 23.

“We beat a good football team on Saturday,” Kill said of the 43-24 win over San Jose State. “But we’ll play a better football team this week. And I think everybody in the Big Ten, from here on out, is a good football team.”
