Instant Analysis: TCU beats Texas 20-13

TCU beat Texas 20-13 Saturday night in Austin.
Here's an instant analysis of the Horned Frogs' Thanksgiving win:
What It Means: Saturday's win, the 600th in school history, improved TCU to 7-4 on the season and 4-4 in Big 12 play. It also knocked Texas out of the league title race.
It Was Over When: Sam Carter intercepted Case McCoy's pass with 1:20 left in the game.
Key Stat: Despite the Longhorns' slew of talented running backs, TCU, mostly without a rushing game the past few weeks, out-gained Texas 217 yards-to-86 yards on the ground. Both of the Frogs' touchdowns came via the run game. Matthew Tucker scored from 2 and 1 yards.
Up Next: TCU faces Oklahoma in its season finale next week at Amon G. Carter Stadium. Kickoff time should be announced Sunday or Monday.
Some more highlights from Saturday night:
Stingy Defense. The Frogs didn't give up a touchdown until late in the game, and, for most of the night, the Longhorns could hardly get anything going on offense. David Ash and the Texas running game was able to move the football early in the game, but interceptions by Jason Verrett and Elisha Olabode thwarted scoring opportunities for the Horns.
Maponga, Fields Shine. Devonte' Fields had four tackles, two of which were for loss including a sack. Stansly Maponga was nearly as good, registering a tackle for loss and .5 sacks. Maponga also recovered fumble in the first half. Both guys were on their game against Kansas State, continually pressuring Collin Klein. Saturday night was no different, as Fields and Maponga caused disruption throughout the game.
Boykin Plays Steady. Trevone Boykin wasn't great, but he was good enough, especially with the way the TCU defense was playing. Boykin was 7-for-9 passing for 82 yards and an interception, but he escaped pressure most of the night, only getting sacked once.
Ash then McCoy then Ash then McCoy. It appears the Texas quarterback problem has come up again. David Ash, who entered Saturday ranked second in the Big 12 in passing efficiency, started before throwing two picks and getting yanked in favor of Case McCoy. Ash then came back in the second half, before struggling some more and giving way again to McCoy, who led the Horns to their only touchdown of the night. It's amazing, really, that Mack Brown, who has perhaps the best job in the country with amazing facilities located in fertile recruiting ground, can't find a solid option at quarterback.
