The No. 3 Sooners have looked invincible more often than not during their 39-game winning streak at Owen Field dating back to 2005.
Saturday night against Texas Tech, they have looked anything but.
The defense is getting shredded by Seth Doege and the Red Raider receivers, and the offense looks out of sorts, missing on blocks, throws and dropping passes.
The Sooners trail, 24-7, entering the third quarter.
A comeback looks anything but imminent. Oklahoma's offense can hang points in a hurry, so it's a very real possibility, but so is a shocking upset.
Alex Torres has a pair of touchdowns on slip screens that were expertly blocked downfield against an Oklahoma defense that looked helpless.
Texas Tech, four-touchdown underdogs, has Oklahoma in a precarious spot. Oklahoma officials told media in the press box that the largest deficit ever erased at home by an Oklahoma team is 15 points against Vanderbilt in 1977.
Oklahoma can hang all the points it wants in the second half, but the defense has to get better first. Another 24 points for Texas Tech's offense in the second half would almost certainly put this out of reach.
Can the Sooners come back? I'm betting on a nailbiting finish either way.
Should be an exciting second half.
