There are still plenty of contenders for a national championship game. What about the Heisman Trophy?

While unbeatens Oklahoma, Miami and Ohio State will try to stay in the title chase Saturday, star players from each team can boost their chances to win college football’s top individual prize.

All three teams are on the road, with running back Quentin Griffin leading No. 1 Oklahoma (8-0) against Texas A&M (5-4), quarterback Ken Dorsey and No. 2 Miami (8-0) taking on Tennessee (5-3), and freshman running back Maurice Clarett and No. 3 Ohio State (10-0) visiting Purdue (4-5).

Griffin, Oklahoma’s smallest player at 5-foot-8, has made the biggest Heisman impact of late.

“He’s gaining momentum and is really playing in a great way right now,” Sooners coach Bob Stoops said. “And we’ll need it the rest of the way.”

Griffin has 487 of his 950 yards in the last three games against Top 25 teams Texas, Iowa State and Colorado. Until last week’s 27-11 victory against Colorado, Griffin had caught a pass in 38 straight games.

The Aggies’ run defense is formidable, allowing 117 yards per game. But Texas A&M has allowed 38 points per game in its last three losses.

Dorsey, despite a 34-1 record as a starter, has not lived up to his preseason hype. He has, though, come through each time the Hurricanes needed him.

In last week’s ragged 42-17 victory against Rutgers, Dorsey sparked a 28-point fourth quarter with two quick TD passes; against West Virginia he threw for a career-high 422 yards in a 40-23 win; and he engineered two fourth-quarter touchdown drives to pull out a 28-27 victory against Florida State.

Dorsey, 16th nationally in pass efficiency, has completed 134 of 244 passes for 2,020 yards and 20 touchdowns. Teammate Willis McGahee, who has 1,034 yards rushing, also is a Heisman contender.

The Vols are looking to end Miami’s school-record 30-game winning streak, and hope their running game of Jabari Davis and Cedric Houston can wear down the Hurricanes.

“Tennessee is big and physical in the offensive line and they have great running backs,” Miami coach Larry Coker said. “We’re trying to get our run defense to be more physical.”

Ohio State travels to West Lafayette, Ind., hoping Clarett is recovered from a left shoulder injury that kept him out last week against Minnesota.

Clarett, who has missed two games and most of a third, still has 1,019 yards and averages 127.4 ypg (ninth nationally, just below McGahee).

Ohio State, though, has excelled on defense. The Buckeyes lead the Big Ten in points allowed (12.8) and yards allowed (305.6).
