LeFevour had a touchdown pass to put the sluggish Chippewas (12-2) ahead with 1:17 left and scored from 13 yards out in the first overtime on the day he moved into second place in the Football Bowl Subdivision's career total yards list.
Vince Agnew blocked Michael Taylor's 31-yard field-goal attempt to start the second overtime and Central Michigan played it conservative before Aguila set a GMAC record with his fifth field goal.
The Trojans (9-4) led much of the game behind DuJuan Harris' three touchdowns. But after taking a 31-19 lead midway through the fourth quarter, they gave up a 95-yard kickoff return to Antonio Brown, then allowed LeFevour to complete 8 of 11 passes for 90 yards before finding Bryan Anderson for a 4-yard score.
LeFevour and the rest of the senior class were dealing with the loss of their head coach for the second time. First, Cincinnati spirited away Brian Kelly three years ago. Then when Notre Dame hired Kelly, the Bearcats came back for Butch Jones.
Interim coach Steve Stripling said there was a momentary sense of disorientation after Jones left, but the players quickly settled down.
"It was just a time of uncertainty, so you're not sure about things," Stripling said. "So we just sat them down and said, 'Hey, look we've had these common goals all year. Let's go back to focusing on those. We're going to make a commitment as a staff to you and you make the commitment to us.' And so after a couple of days it was fine."
