"It's huge for our program, to get a win like this after no one gave us a chance all year," Knight said. "We've got to ride this into next year. We can't settle with this. ... We want the big one."
Oklahoma (11-2) needed him to play that well in the 80th Sugar Bowl, the first in which quarterbacks for both teams threw for more than 300 yards.
His Big 12 team vanquished an Alabama (11-2) squad that had been ranked No. 1 much of the past three seasons, winning the previous two national titles before its shot at a third straight was derailed by Auburn on the last play of the Iron Bowl in late November.
Coach Nick Saban didn't find his team, favored by 16 points, was too deflated from its loss to Auburn to play up to its standard.
"I actually thought that the players responded in practice pretty well for this game," Saban said. "We put over 500 yards of offense up. Somebody had to do something right. I don't think that we played as well on defense as we're capable of or should have."
McCarron passed for 387 yards and two TDs, but his two interceptions set up Oklahoma TDs. He was also sacked seven times, fumbling on the last one, and Geneo Grissom returned his second recovery of the game 8 yards for a score, sealing Alabama's first two-game skid since its Sugar Bowl loss to Utah in January 2009.
"Put it all on me. I had two turnovers, (Oklahoma) ended up scoring 14 points, and we lost by 14," said McCarron, who won 36 of his first 38 games before losing his last two. "I wish it wouldn't have happened, but I'll definitely take the loss and definitely take the blame, because a lot of it is probably my fault."
