ARLINGTON, Texas — Some thought this game wasn’t losable for the Oklahoma Sooners. Brigham Young proved otherwise with a 14-13 upset Saturday night at Jerry Jones World, and you can blame it on the guys who weren’t there. And I don’t mean Sam Bradford (for a half) or Jermaine Gresham. Turns out, those departed offensive linemen who protected Sammy B. so well — Duke Robinson, Phil Loadholt, Brandon Walker and Jon Cooper — were not so easily replaced after all. The Sooners scored just 10 points with Bradford, before he went down and out on the first half’s final play from scrimmage, and the O-line’s troubles — rampant penalties, no blowing BYU off the ball — continued in the second half, when rookie Landry Jones needed all the help he could get. Holding. False starts. Penalties came early and often. Cory Brandon alone was flagged six times. Each of Jones’ first two possessions started with major penalties on first down. First-and-24 and first-and-20 is no way to get a freshman quarterback settled. And when the Sooners needed their beefeaters the most, they failed miserably. With Jones trying to direct a last-ditch drive, OU offensive coordinator Kevin Wilson, who continually touted his line in August, didn’t have enough confidence to take the pressure off Jones and run the ball. Time was available, but Wilson ordered a pass on seven of eight snaps. Jones produced two first downs but had no magic. And the final penalty was perhaps most fatal — another Brandon false start on 3rd-and-9 from the BYU 32-yard line. That made it 3rd-and-14, and after an incompletion, OU was forced to let Tress Way try a 54-yard field goal. It was a little short and a little left. It would have been a lot more interesting from 49 yards out. The line was not totally to blame. Veterans DeMarco Murray and Ryan Broyles each lost fumbles, doubling the number the Sooners lost as a team in all of 2008. Receivers dropped a few balls. Bradford, whose Heisman repeat hopes almost surely are gone now that he’s likely to miss a few games, threw for only 96 yards in the first half. Jones looked neither promising nor overwhelmed. He was so-so on a big stage in a crucial situation. Jones will get better, though the Miami game on Oct. 3 suddenly looks rough for the Sooners if Bradford doesn’t return. Do not blame the OU defense, even for BYU’s fourth-quarter drive, which went 16 plays and 80 yards and was spiced by quarterback Max Hall, who produced several escapes on third or fourth down. The Sooner defense played well enough to win. Fourteen points should be good enough. Someone asked about the national championship race after the game. That’s silly to even think about. Win or lose this BYU game, if this line can’t perform better than this, the Sooners stand no chance against Texas, Bradford or not.
