But drop a few dominoes - Iowa's 24-16 win over Michigan, Northwestern's 28-25 upset of Nebraska - and Iowa is relevant again in the Big Ten race.
If the Hawkeyes defeat Big Ten Legends Division leader Michigan State this week and Purdue and Nebraska on the road in the final two weeks of the regular season, Iowa is playing for a Big Ten championship.
That's a lot of "ifs." Still, any other year in the Big Ten's history and Iowa would be all but irrelevant by now.
"Last week, basically, we were toxic, and now people are talking about conference races again," Hawkeyes coach Kirk Ferentz said. "We won one game. We have three really tough games ahead of us. That's what we're worried about at this point."
Iowa is by no means a favorite for the Big Ten title; the road ahead is difficult. Michigan State is second in the Big Ten in total defense despite a loss to Nebraska and a close call with Minnesota, and even if Iowa can defeat the Spartans in Iowa City, the Hawkeyes have been a different team on the road, where they lost to Iowa State, Penn State and Minnesota.
Still, there is reason for hope. In the past four games, tailback Marcus Coker has been running more decisively, Ferentz said. He has been one of the top offensive players in the Big Ten in that span, rushing for 647 yards and eight touchdowns.
Iowa's defense, which has been lackluster by its standards, had its best performance of the season last week, holding Michigan to 323 total yards.
While Iowa frustrated Wolverines quarterback Denard Robinson, Michigan State presents different challenges with a pro-style offense and a better passer in Kirk Cousins.
The only one-loss team in conference play in the Legends Division, Michigan State, too, is preparing for a stretch run that it hopes will end with a Rose Bowl berth. The Spartans put all players off-limits for media interviews this week, its second media ban of the season. The first was the week before Michigan State's 10-7 win over Ohio State on Oct. 1.
Michigan State has not won in Iowa City since 1989. That seven-game losing streak includes Michigan State's only regular-season loss last season.
"There's been so much talk about divisional play and conference races, but the one thing that hasn't changed is that the more you win, the better off you are, and the more you lose, the worse off you are," Ferentz said.
Best matchup: Illinois DE Whitney Mercilus vs. Michigan QB Denard Robinson. Containing and pressuring Robinson has been the key to slowing Michigan's offense the past two seasons, especially later in the season. Mercilus, the Big Ten's leader in sacks, could help this effort as Illinois tries to end a three-game losing streak.
Player on the spot: Nebraska RB Rex Burkhead. Burkhead took a hit early in last week's lost to Northwestern game, Huskers coach Bo Pelini said, and it looks to have bothered him the rest of the game. Burkhead had his second-lowest rushing total of the season: 49 yards on 22 carries. Nebraska needs him to return healthy against Penn State's defense.
Keep an eye on: Michigan State's tailback rotation. Edwin Baker rushed for 1,201 yards and 13 touchdowns last season. This season, he's struggling to approach even half of that yardage total. He rushed for 167 yards against Michigan on Oct. 15, but in the past three games, Baker has run for 73 yards on 29 carries. He also has lost a fumble in three of the past four games. In his place, Le'Veon Bell has been Michigan State's top rusher, with 241 yards and two touchdowns on 43 carries in the past three games.
Numbers game: Minnesota QB MarQueis Gray has been hot of late, going 30-of-49 passing for 488 yards and four touchdowns against Iowa and Michigan State. He also rushed for 132 yards and a touchdown in this two-game span. Gray set career highs in completions (19), attempts (49) and yards (295) in the loss to Michigan State. Gray was recruited as a quarterback but spent last season as a wide receiver.
