ANN ARBOR, Michigan (Ticker) -- As Michigan's first true freshman quarterback in nearly 30 years, Chad Henne stayed cool and let Josh Betts make the mistakes.
Henne threw two touchdown passes to Braylon Edwards and kept his composure in his debut and No. 7 Michigan intercepted Betts four times in a 43-10 victory over Miami of Ohio, which saw its 14-game winning streak come to an end.
"I'm naturally pretty calm," Henne said. "There was some nervousness at the beginning, but then I let my personality take over."
Two days before Michigan's 125th season opener, coach Lloyd Carr opted for Henne over Matt Gutierrez, who has soreness in his throwing arm. Henne became the first true freshman to start the season at quarterback since Rick Leach in 1975.
"He tried to smile but he got only halfway," Carr said. "You couldn't ask any more of him than what he did today. He made one mistake - that interception - but considering running out on that field today when he basically just finished with the junior-senior prom, I thought he did a fine job."
A native of Wyomissing, Pennsylvania, Henne was hesitant early but took off the reins as the game progressed. He completed 13-of-24 passes with one interception as Carr showed great faith in him.
"I'd give him an A," Edwards said. "He's a true freshman starting his first game in this environment, and he played like a senior."
"Every day I tried to eliminate the mistakes I made the day before, so if I got the chance I'd be ready to go," Henne said. "This is a great opportunity for a freshman with the tradition here. I just wanted to go out and do my best and keep up the tradition whether I'm the starter, the backup or third string."
Henne was much more cool under pressure than Betts, who played in nine games last year as Ben Roethlisberger's understudy and already had one game under his belt, a 49-0 win over Indiana State last week. He was 18-of-36 for 201 yards but appeared rattled and committed five turnovers, all of which led to scores by the Wolverines.
"I told him he can't say, 'Forget it.' He needs to learn from this," Miami coach Terry Hoeppner said.
"From the beginning we thought turnovers would be a big part of the game," Betts said. "If we didn't turn it over and put our defense in a hole, they would have held them to under 20 points. But give them credit, they made big plays."
Miami's winning streak was the longest in the nation and school history. It had not lost in more than a year since a 21-3 setback to Iowa on August 30, 2003.
"Ben Roethlisberger was on the sidelines and said this reminded him of Iowa last year and we'll probably go 12-1," Hoeppner said.
Betts' biggest mistake came after Ryne Robinson had gotten the RedHawks back in the game with a pair of long punt returns in the fourth quarter. The first was 70 yards and set up Mike Smith's one-yard TD run that made it 24-10. The second was 44 yards and put Miami at the Michigan 16.
Throwing to his right, Betts was picked off by Earnest Shazor, who raced 88 yards untouched to the end zone for a 30-10 lead with nine minutes to go. It was the third-longest interception return in Michigan history.
"The play they intercepted and ran back was a special play we put in just for this game," Hoeppner said. "The play was called Wolverine. We probably won't use it again."
On the next possession, Markus Curry intercepted Betts for the second time. That led to Henne's 13-yard TD pass to Edwards, who made a juggling catch in the end zone.
"I'm not surprised we had that many turnovers," Shazor said. "We've had 30 or 40 in practice and it just carried over into the game."
David Underwood had 61 yards and a pair of scores on 22 carries as he stabilized the offense until Henne got comfortable. That came early midway through the third quarter, when he found Edwards with a 24-yard TD toss for a 24-0 lead.
A 38-yard interception return by Ryan Mundy positioned Garrett Rivas for a 31-yard field goal that opened the scoring with 6:31 left in the second quarter. Curry's first pick and 21-yard return led to Underwood's first TD run less than two minutes later.
A fumble by Betts led to Underwood's second one-yard TD run that made it 17-0 just 2:35 into the second half.
