INDIANAPOLIS — Michigan coach Jim Harbaugh celebrated his return to the sideline Saturday by hugging players and evasively running to avoid a Gatorade bath.

Blake Corum and J.J. McCarthy were already reflecting on bigger goals.

And when the confetti came streaming down over the Wolverines, they made sure everyone knew they were no longer the nation’s second-best team.

Corum scored twice and the defense pitched a rare shutout as No. 2 Michigan routed No. 18 Iowa 26-0 for its third straight Big Ten title game, a third straight playoff berth and likely the top seed in the College Football Playoff.

“We set our goals earlier this year and this is another one we checked off,” Corum said after rushing for 52 yards on 16 carries and tying Anthony Thomas’ career record for TD runs with 55.

And with No. 1 Georgia falling to No. 8 Alabama in the Southeastern Conference title game, Michigan (13-0, No. 2 CFP) is finally poised to reach No. 1 after spending 13 of 14 weeks at No. 2. Michigan lost each of its previous two semifinal appearances and hasn’t won a national title since 1997.

Iowa (10-3, No. 16) never had a chance.

Harbaugh’s return meant he could finally savor a milestone moment on the sideline with his players after serving three-game suspension for an alleged sign-stealing scheme. He missed the 1,000th victory in program history and last week’s 30-24 division-clinching victory over archrival Ohio State.

Michigan fans booed loudly as first-year Big Ten Commissioner Tony Petitti presented the championship trophy and appeared not to even look at Harbaugh after he became the first coach in league history to win three straight outright conference championships. It’s also a school first.

Harbaugh didn’t seem to care about Petitti’s reaction, though.

“It made me feel super great,” Harbaugh said of the feat. “I’ve got one question for the Michigan Nation, who’s got a better team than us?”

The Wolverines extended their school record of consecutive wins over Big Ten foes to 25 as J.J. McCarthy went 22 of 30 for 147 yards.

For the Hawkeyes, it was more of the same.

While the defense held stout — allowing the TDs on drives of 5 and 6 yards and four field goals — the offense produced just 155 yards and became only the second team in conference title game history to be shut out in the final season of the East-West division format. Ohio State opened that era with a 59-0 rout over Wisconsin 59-0 in 2014.

Deacon Hill was 18 of 32 with 120 yards and the Hawkeyes rushed for 35 yards on 24 carries. The loss snapped a four-game winning streak and marked the second in three years Iowa lost the title game to Michigan by more than 25 points.

The difference Saturday was simple.

The Wolverines capitalized on Iowa’s errors; the Hawkeyes never did.

“Tonight certainly wasn’t our night,” Iowa coach Kirk Ferentz said. “We knew we came in here needing to play pretty much a flawless game. Obviously, we didn’t do that, didn’t do a great job protecting the football, and a couple of other situations. It was a disappointing tonight.”

Michigan took a 10-0 lead with a 35-yard field goal on its first possession and Corum’s 3-yard run on its next, two plays after Semaj Morgan broke free for an 87-yard punt return to set a Big Ten title game record.

Corum is the only FBS offensive or defensive player who has scored in every game this season.

He scored again early in the second half when a replay review overturned an incompletion and ruled it was a fumble. Michigan recovered and outgoing Iowa offensive coordinator Brian Ferentz compounded the problem by drawing a penalty for unsportsmanlike penalty, moving the ball to the 6. following. That made it 17-0.

“I’ve made it the last two months without getting fined, so I’ll try again,” Ferentz said. “I’m really struggling with our replay system. Tonight what I was told, the arm was going forward, but the hand wasn’t, which I’m not sure if that’s possible mechanically.”

Michigan closed it out with three field goals, the final one being a 50-yarder from James Turner to set a title-game record.

Iowa’s best scoring chance came after a 25-yard punt put it at the Michigan 38. Three plays later, though Jaziun Patterson lost a fumble at the 30.

THE TAKEAWAY

Iowa: Two streaks continued. The Big Ten West closes out the league’s division era going 0-10 in title games and the Hawkeyes still have not won a conference crown since 2004. Few gave Iowa and its low-scoring offense any chance Saturday night. Neither did the Wolverines.

Michigan: Harbaugh missed six games this season because of suspension and yet Michigan heads into the postseason undefeated for the second straight year. Getting the No. 1 seed could lead to a matchup with SEC champ Alabama, Big 12 champ Texas, two-time defending national champ Georgia or perhaps even archrival Ohio State.

It has already been a wild Championship Week — and there are still two games to go. No. 8 Alabama taking down No. 1 Georgia in the SEC Championship Game has all but punted the Bulldogs from competing for a third straight national championship — barring some more upsets — and put the Crimson Tide in a head-to-head debate with the one team that defeated them this season, No. 7 Texas.

The Longhorns, which thoroughly took down the Tide by 10 points on the road at Bryant-Denny Stadium back in Week 2, completed their campaign with a dominant 49-21 win over No. 18 Oklahoma State in the Big 12 Championship Game.

With only three undefeated Power Five teams remaining following the Georgia loss, Texas is now projected as the fourth seed in the playoff over Alabama by virtue of the ‘Horns head-to-head victory back on Sept. 9.

The CFP Selection Committee will use criteria including championships won, strength of schedule, head-to-head results (if applicable) and comparative outcomes against common opponents in making its determinations. Texas and Alabama both won conference titles Saturday, and while the ‘Horns have a tougher strength of schedule, the Tide have more wins over CFP-ranked teams — four (including over No. 1) vs. three.

The SEC has sent at least one team to every playoff since the event’s inception; however, no program has made the playoff when placed No. 7 or lower in the penultimate CFP Rankings. Both Texas and Alabama will look to buck the latter trend.

The Tide’s best remaining path to ensuring themselves a spot in the playoff is a loss by Michigan (vs. Iowa) or Florida State (vs. Louisville) in their respective conference title games Saturday night.

Another significant development took place in determining the Group of Five representative in the New Year’s Six. SMU upset No. 22 Tulane in the AAC Championship Game on Saturday, handing the Green Wave their second loss of the season, while No. 24 Liberty remained undefeated with two-touchdown win over New Mexico State on Friday in the Conference USA Championship Game.

As such, I project Liberty to jump Tulane in the final CFP Rankings, emerging as the top Group of Five team and earning a spot in the Fiesta Bowl against Missouri.

The body of a traveling nurse from Michigan who went missing two weeks ago has been found in California.

Ann Herford, 66, of Elkin, west of Bad Axe in the Thumb region, was reported missing Nov. 15 after not showing up for work at Adventist Health in Sonara, Calif., the Calaveras County Sheriff’s Office said in a Facebook post.

Herford had last been seen near a trailhead of the Arnold Rim Trail, a densely forested area in Arnold, California.

Her body was found Thursday morning north of where her car was originally parked, not within the trail system, in a “35-degree sloped hillside beneath heavy tree canopy and dense foliage,” the sheriff’s office said.

Due to the terrain, her body was transported by a California Highway Patrol aircraft, the sheriff’s office said.

Herford’s family told authorities she enjoyed hiking but lacked wilderness survival skills and never planned to hike for more than a few miles at a time.

The Air National Guard, U.S. Army Aircraft, numerous state and county departments and volunteers assisted in air and ground searches.

The Calaveras County Sheriff’s Office said detectives are still investigating the incident, but the circumstances of Herford’s death do not appear suspicious.
