When Trevor Knight starts Oklahoma's season opener against Louisiana-Monroe on Saturday, he'll become the ninth freshman to start at quarterback for the Sooners. Here's a look at how the others fared:
As a freshman (2009): Jones was pressed into duty when Sam Bradford went down to an injury in the season-opener against BYU and started the next three games before Bradford returned. Bradford was reinjured a game later and Jones started the rest of the season, throwing for a total of 3,198 yards 26 touchdowns.
Career: Jones shattered Bradford's school career passing records, throwing for 16,646 yards and 123 touchdowns.
Starting debut: After coming on in the loss to BYU, Jones started a week later against Idaho State, throwing for 286 yards and three touchdowns in a 64-0 blowout.
As a freshman (2007): In his debut, Bradford broke Josh Heupel's record for passing yards in a half with 350 yards and tied Jason White's record with 18 consecutive completions. He finished the season throwing for 3,121 yards and 36 touchdowns.
Career: Bradford won the Heisman Trophy as a sophomore, throwing for 4,720 yards and 50 touchdowns. He set school career records in yards (8,403) and touchdowns (88) before being injured twice as a junior and declaring for the draft. He was the No. 1 overall pick in 2010.
Starting debut: In a 79-10 rout of North Texas, the Putnam City North product threw for 363 yards and three touchdowns no interceptions.
As a freshman (2005): Paul Thompson was the starter in the season opener, but Bomar played in an opening loss to TCU, then took over as the starter. Bomar threw for 2,018 yards and 10 touchdowns, helping the Sooners to a Holiday Bowl win over Oregon.
Career: Bomar was kicked off the team just before his sophomore season and wound up at Sam Houston State.
Starting debut: The Sooners needed a strong performance from Adrian Peterson (220 yards on 32 carries) to get past Tulsa, 31-15, in the season's second game. Bomar completed just five of 13 passes for 42 yards and two interceptions and didn't attempt a pass in the second half.
As a freshman (1998): After playing briefly in relief in a season-opening win over North Texas, Sills didn't play again at quarterback until the seventh game.
