ANN ARBOR, Michigan — A Hail Mary would not have helped BYU. The No. 22 Cougars needed much more than that.
BYU came to the Big House after a strong start this season and spoiled it with a 31-0 loss to Michigan on Saturday.
"They outmanned us, outplayed us, outperformed us," quarterback Tanner Mangum said. "They just, you know, took it to us."
The Cougars (2-2) have back-to-back losses, including a one-point setback at then-No. 10 UCLA. That came after a come-from-behind win against a then-ranked Boise State and beating Nebraska on a Hail Mary.
"That was the best team we played to this point not only physically, but execution wise," Cougars coach Bronco Mendenhall.
Mangum looked like a freshman for the first time this season, connecting on just 12 of 28 passes for 55 yards. Entering the game, Mangum had completed 63 percent of his passes for 664 yards with four TDs in two-plus games in place of injured teammate Taysom Hill.
"Not very pleased with my performance," Mangum said. "As the quarterback, I take that on me. It was such a poor outing on offense, that's not what we want to accomplish, it's not what we stand for."
BYU was shut out for the first time in 143 games, dating to a 3-0 loss to rival Utah in 2003. During the Cougars' streak of scoring in every game for more than a decade, they averaged 32 points.
Against three notable opponents this year, BYU was averaging 310 yards passing and 122 yards rushing. Against Michigan, the Cougars were held to fewer than 100 yards until the final minute at the Big House.
"To only give up 105 yards, I'm not sure I've been a part of one of those," Michigan coach Jim Harbaugh said.
BYU was held to its lowest total on offense since at least 1996.
Jake Rudock ran for two touchdowns and threw for another one during a first half in which Michigan did all of its scoring.
The Wolverines (3-1) have won three straight after their season-opening loss at Utah. They were 1-9 in their last 10 games against ranked opponents — the lone victory was against Notre Dame two-plus years ago — and had won just three of 22 games against teams in The Associated Press poll since midway through the 2009 season.
"It feels good to finally beat a ranked team," running back De'Veon Smith said. "We have to keep the momentum going and keep making statements."
Smith ran for 125 yards on 16 carries, including a tackle-breaking, 60-yard TD, before leaving the game late in the third quarter after appearing to hurt his right ankle. After being evaluated in the locker room, Smith was wearing a walking boot as a precaution. X-rays were negative.
"I expect to play next week," he said.
Michigan opens Big Ten play at Maryland.
The Cougars, meanwhile, will host Connecticut and plan to be very fired up to bounce back from a humbling defeat.
"That's just going to motivate us to work harder this week so we can be better next Friday," Mangum said.
