It was the tale of two halves for a Texas coaching staff that has a lot of questions to answer this week after being outcoached in the second half.
The Texas defense seemed to be finally playing up to its potential in the second quarter. Geno Smith was getting clobbered in the backfield and Alex Okafor was able to force a turnover that led directly to a Texas touchdown.
The Mountaineers were on the ropes heading into halftime, and then they were standing over a knocked out Texas defense. Diaz was never able to find a formula for stopping Andrew Buie and was schooled on all five of West Virginia's fourth-down tries. Okafor was able to make another play late, but Diaz was outmarted by WVU head coach Dana Holgorsen all night.
Diaz will take more heat than offensive coordinator Bryan Harsin, but Harsin is equally to blame for the loss.
Daje Johnson touched the ball three times in the first quarter for 54 yards and never saw the field again. D.J. Monroe, who had three touchdowns coming into tonight's game, did not touch the ball. And Harsin elected to give Joe Bergeron, who was only averaging 2.6 yards per carry, the ball in the red zone rather than trust David Ash to throw it or let Johnathan Gray run the highly effective Wild formation.
Harsin got away from what was working and never gave his big-play threats much of a chance in the second half as West Virginia's big-play guys started asserting their will. The trust he showed in Ash and Gray during crunch time last week was nowhere to be found against West Virginia, and the team suffered for it. In a game that was this close, these decisions make a major difference.
