Michigan’s Denard Robinson has Notre Dame on the run

In Denard Robinson’s two college starts, both this season, the sophomore has established Michigan quarterback records for rushing yards and total offense.

He accounted for 502 yards Saturday in a 28-24 win over Notre Dame, passing for 244 yards and rushing for 258 yards — including an 87-yard touchdown run in the second quarter that stands as the longest in the history of Notre Dame’s football stadium.

Robinson should now be in the middle of any conversation about the Heisman Trophy. And Notre Dame quarterback Dayne Crist proved that he might be just as valuable to his team.

The former Sherman Oaks Notre Dame High star completed five of seven passes and ran for 30 yards in leading the Irish on a 71-yard touchdown drive on their first possession.

But Crist hit his head on the turf after one of his runs, and he spent the rest of the first half on the bench. Without him, Notre Dame’s offense stalled — backups Tommy Rees and Nate Montana each had passes intercepted — and Michigan took a 21-7 halftime lead.

Crist returned in the second half and finished with 277 yards and two touchdowns passing, completing 13 of 25 with one interception.

Big Red zone

Taylor Martinez attended three high schools — Norco, Cajon and Corona Centennial — in four years, but it looks like he’ll be settling in at one college.

Martinez, a redshirt freshman, beat out incumbent Zac Lee to become the starting quarterback for No. 6 Nebraska, and it looks as if he has a hold on the job. He ran for 157 yards and two touchdowns and passed for 106 yards as the Cornhuskers defeated Idaho, 38-17.

One of his touchdown runs covered 67 yards — the longest ever by a Nebraska freshman quarterback. The record was held by Eric Crouch, who scored on a 59-yard run in 1998. Crouch went on to win the 2001 Heisman Trophy.

Martinez has 284 yards rushing in two games, and is averaging 13.5 yards a carry.

Chomp on this

Another easy win over an outmanned opponent, but more early struggles for Florida’s offense.

The Gators had only 37 yards in the first quarter and trailed South Florida, 7-0, until scoring 44 seconds before halftime.

But just as he did last week against Miami of Ohio, NCAA sprint champion Jeff Demps jump-started Florida with a long run to the end zone. Demps’ 62-yard run midway through the third quarter put the Gators in the lead and they cruised from there, winning 38-14.

Demps finished with a career-high 139 yards rushing and 255 all-purpose yards.

Trojans transfer update

Emmanuel Moody left USC in search of a better opportunity to run the ball. Now he’s at Florida, and again sharing time — this time with Demps.

Moody is getting his chances, though. He had 54 yards rushing in 14 carries against South Florida and his 19 carries through two games is equal with Demps.

The difference: Moody’s carries have gone for 59 yards; Demps’ for 237.

Why hurry?

Colorado has been negotiating with the Big 12 Conference about a buyout that would allow the Buffaloes to join the Pacific 10 Conference next year instead of in 2012. Football coach Dan Hawkins might tell his side not to rush things.

California, which is expected to finish somewhere near the middle of the Pac-10 this season, crushed Colorado, 52-7. Reaction? Buffs receiver Scott McKnight was blunt: “This was the most embarrassing game of my life.”

Good news for Colorado before the game, though: Pac-10 Commissioner Larry Scott said he was pessimistic the Buffs would join the Pac-10 before 2012.

Oh, brother

Oklahoma had little trouble figuring out Florida State’s defense in a 47-17 win — maybe because the Seminoles’ scheme was devised by Mark Stoops, brother of Oklahoma head coach Bob Stoops.

It was the first time Bob had competed against any of his three college-coach brothers.
