So that’s why Joe Tiller was so mad.

Redshirt freshman receiver Roy Roundtree had a career day for Michigan on Saturday, catching 10 passes for 126 yards.

Roundtree committed to the Boilermakers two years ago only to have a last-minute change of heart and sign with the Wolverines. When he did, Tiller, the ex-Purdue coach, said Roundtree was lured by “a guy in a wizard hat selling snake oil.”

Roundtree said Saturday that wasn’t the case.

“I always wanted to be a Michigan man,” said Roundtree, who wasn’t recruited by former Michigan coach Lloyd Carr’s staff. “I had an uncle that played for Ohio State (receiver Jeff Graham) and after the decision making, before signing day, I called him and he told me, ‘Hey, it’s Michigan. Great education.’

“That’s what I basically based mine off of. When I took my visit, I’m like, 'Yeah, they got more helpful things at Michigan than Purdue.'"

Roundtree, who made his second career start in place of the injured Martavious Odoms, said Michigan coach Rich Rodriguez recruited him at West Virginia.

"But I told him, 'Nah, I ain't going to West Virginia,'" Roundtree said.

Onside kick pays off for Purdue

In a game that had its share of twists and turns, Hope's choice to implement an onside kick after the Boilermakers trimmed the deficit to 30-24 came up big.

After recovering the kick, Purdue needed only one play - a 54-yard Joey Elliott scoring pass to a wide-open Cortez Smith gave Purdue the lead for good.

Afterward, Michigan's players understood the severity of the mental mistake.

"They got a little bit of momentum after (the onside kick) and it kind of went down from there," junior cornerback Donovan Warren said. "That's on the players. Guys just have to be more aware of the situation and looking at the ball and doing their assignment. It's the little things that add up. That's something little you wouldn't expect."

Replay on the lateral was clear

Carlos Brown’s forward lateral was too close to tell on the field, referee Todd Geerlings said, so the replay booth called for a review.

Initially, the play on the field was called a legal lateral, with Brown hitting offensive lineman Mark Huyge for a first down.

“The replay official saw that the ball, when it left his hand to the point where it touched the receiver’s hand was clearly forward from the 13- to the 12-yard line,” Geerlings said. “That’s why we had an illegal forward pass from the spot of that pass.”

Geerlings said he couldn’t comment on the Junior Hemingway punt catch interference call, where it appeared Hemingway tripped over his own feet to start the drive because it was a judgment call.

Injury report

Quarterback Tate Forcier wore an ice bag on his left knee and walked with a heavy limp after Saturday's 38-36 loss to Purdue, but Forcier said he wasn't badly injured on his third-quarter touchdown run.

"I'm fine," said Forcier, who re-entered the game and finished 15 of 24 for 212 yards passing.

Brown played sparingly Saturday because of knee tendinitis. Brown did not play in the first half and only came on after Michigan fell behind 38-30. He finished with two carries for 13 yards.

Last week, Brandon Minor saw sporadic playing time because of a lingering high ankle sprain.

Patrick Omameh also made his first career start at right guard for Michigan, and Kevin Leach had an interception in his second straight start at middle linebacker over Obi Ezeh.

J.B. Fitzgerald played most of the game at weak-side linebacker in place of Jonas Mouton, who was benched for a broken coverage on Purdue's 35-yard game-opening touchdown pass from Joey Elliott to Ralph Bolden.
