Oklahoma has two of the top seasons by a freshman quarterback in college football history. Jamelle Holieway led the Sooners to the national title as a true freshman in 1985, and Sam Bradford put up huge numbers as a redshirt in 2007. Here's a look at a few of the other top seasons by freshman quarterbacks:
Johnny Manziel, Texas A&M (2012): Manziel, like Trevor Knight a Texas native, became the first freshman to win the Heisman Trophy last season. He threw for 3,706 yards and 26 touchdowns and rushed for 1,410 yards and 21 scores, breaking Cam Newton's SEC record for total yards. Manziel's season included a 41-13 destruction of OU in the Cotton Bowl.
Robert Griffin III, Baylor (2008): Baylor still sat near the bottom of the Big 12, but Griffin showed signs of being the quarterback that led the Bears back into bowl position. He threw for 2,091 yards and 15 touchdowns while throwing just three interceptions and ran for 843 yards and 13 scores in his first year.
Terrelle Pryor, Ohio State (2008): Todd Boeckman started the season as the Buckeyes' starter, but Pryor took over following a loss to USC in the third game. Pryor threw for 1,311 yards while completing more than 60 percent of his passes and rushed for 631 yards and six touchdowns to help Ohio State to a Fiesta Bowl berth.
Colt McCoy (2006): After replacing Vince Young at quarterback, McCoy helped get the Longhorns back in the national championship picture as a freshman, throwing for 2,570 yards, 29 touchdowns and just seven interceptions. After he started out 9-1 as a starter, including a 28-10 win over Oklahoma, McCoy was hurt against Kansas State and the Longhorns dropped that game and the Texas A&M game to end the regular season.
Chad Henne, Michigan (2004): Henne never matched his freshman numbers with the Wolverines, throwing for 2,743 yards and 25 touchdowns in helping Michigan to a 9-3 season.
Michael Vick, Virginia Tech (1999): The redshirt freshman electrified college football, helping the Hokies to an undefeated regular season while finishing third in Heisman Trophy voting. In a Sugar Bowl loss to Florida State for the national championship, Vick still put up 322 yards of total offense.
