Trailing for the first time all game, the Seminoles quickly marched into field goal range with a 66-yard kick return by Keith Gavin.
Quarterback Deondre Francois, who had one of his roughest nights, hit Nyquan Murray for 12 yards and the winning touchdown with 36 seconds to play to lead to bring the Seminoles back.
Senior defensive end DeMarcus Walker led the tackle-for-loss-charge in his final game as a Seminole. He had the second-most receiving touchdowns on the team for the season with six.
"I couldn't be any prouder of any team I've ever coach", FSU coach Jimbo Fisher said.
And yet Butt said after the game that he doesn't regret playing in the Orange Bowl.
Michigan All-American linebacker Jabrill Peppers was a last-minute scratch from Friday night's Orange Bowl at Hard Rock Stadium because of a hamstring injury.
The Heisman Trophy finalist could very well have played his final game in a MI uniform in the Wolverines' loss to Ohio State. The Seminoles held a MI team that averaged 6.06 yards per play and 439.3 yards per game entering Friday to 3.4 yards per play and 252 total yards, the Wolverines' second lowest yardage mark this season.
Bill Durham, a 1965 FSU graduate, created the idea for Renegade's involvement in Seminoles home football games.
Florida State lost sophomore receiver Auden Tate to a shoulder injury in the first half. Francois' 92-yard touchdown to Murray was the longest touchdown pass in Orange Bowl history.
"We had a kickoff out of bounds", Fisher said.
Then there was the bonehead play that Murray made. This came from a competent mix of keeping Michigan's quarterback, Wilton Speight, on edge in the pocket with pressure and with solid run defense which held UM to 2.5 yards per carry as a team.
The wild first half was full of problems for the Wolverines as Florida State led, 20-6, at halftime.
MI tight end Jake Butt was seriously injured on a tackle after getting the Wolverines into the red zone on a 16-yard catch in the second quarter. At least briefly, until Florida State star tailback Dalvin Cook ripped it away with a 71-yard run.
"The offense in the first half, it was tough sledding", Harbaugh said.
Michigan's offense lacked even those infrequent breakthroughs and settled for three field goals, including one when Murray's muffed punt gave the Wolverines the ball at the Florida State one-yard line. Francois threw for 222 yards and two touchdowns, plus the interception that McCray returned for the third-quarter touchdown.
Cook finished the night with 207 total yards, including 145 on the ground to beat his own FSU single-season rushing record.
"I still haven't made my decision yet", the junior told reporters.
