INDIANAPOLIS — Donovan Edwards' quick-hitting sprints changed everything for No. 2 Michigan. Again.
Now they're hoping it propels them toward another championship.
Edwards ran for 185 yards and a touchdown, J.J. McCarthy threw for three scores and Michigan beat Purdue 43-22 on Saturday night in the Big Ten championship game for its second straight conference title and a likely No. 2 playoff seed.
College football's winningest program has the first 13-win season in school history. Two more victories would give the Wolverines (13-0, No. 2 CFP) their first national championship since 1997 — even without Heisman Trophy candidate Blake Corum because of a season-ending left knee injury.
"He's the best running back in college football and he deserves the Heisman. If he hadn't gotten hurt, he would have easily won the Heisman so this is for Blake Corum," Edwards said after being named the game MVP. "I think it's kind of self-explanatory what our goals are. I believe we've talked about them all year I don't think much more needs to be said."
Those goals appeared to be in jeopardy just last week when Corum managed to play just one series against rival Ohio State.
But Edwards stole the show, shredding the Buckeyes for 216 yards and two scores and was every bit as good in his encore — just hours after Corum posted on Twitter he had undergone knee surgery.
Edwards broke open this game with a 60-yard on the first play of the second half to set up one score. He added a 27-yard TD sprint on Michigan's next series to make it 28-13 and Purdue (8-5) never recovered from the seven-play onslaught after trailing 14-13 at halftime.
"They didn't panic when the game was close in the third quarter," Boilermakers coach Jeff Brohm said. "They came out, ran the ball and imposed their will."
While Edwards was the ringleader, he had plenty of help.
McCarthy was 11 of 17 with 161 yards. Kalel Mullings scored twice on short runs and Ronnie Bell caught five passes for 67 yards and one TD.
But even they knew the difference Saturday was Edwards.
"You put anyone back there, they're going to get yards," McCarthy said. "But Donovan is a special back, a special guy and I'm glad he's on our side."
Purdue quarterback Aidan O'Connell and receiver Charlie Jones helped the Boilermakers make it interesting for a while.
O'Connell was 32 of 47 with 366 yards and two interceptions after missing some practice time early this week to mourn the death of his oldest brother. Jones, who lost to Michigan in last year's game while playing for Iowa, had 13 receptions for 162 yards.
It just wasn't enough.
"We were going to have to play a near-perfect game to win," O'Connell said. "We turned the ball over and didn't score (enough) touchdowns."
Michigan showed no signs of a hangover after last week's rout over the Buckeyes, taking a 7-0 lead on its opening possession with a 25-yard TD pass from J.J. McCarthy to Colston Loveland.
Purdue answered with Devin Mockobee's 1-yard scoring run to tie the score then took the lead on Mitchell Fineran's 33-yard field goal.
Michigan retook the lead on McCarthy's 7-yard TD pass to Luke Schoonmaker and Edwards helped them put it away while holding the Boilermakers to just three second-half field goals.
