LUBBOCK, Texas (AP) - This time, West Virginia's shoddy defense was too much for Geno Smith to overcome.

Smith directed the Mountaineers' prolific attack to shootout victories over Baylor and Texas, becoming a contender for the Heisman Trophy along the way and extending his team's unbeaten run. But that terrific start ended Saturday when West Virginia was steamrolled by an unrelenting Texas Tech offense.

Seth Doege threw for a career-high 499 yards to lead the Red Raiders to a 49-14 victory. West Virginia gave up 676 total yards, and that's its second-highest total this season.

Mountaineers coach Dana Holgorsen said it was a ``poor'' defensive performance.

West Virginia dropped 12 spots to No. 17 when The Associated Press Top 25 was released Sunday. No. 18 Texas Tech is ranked for the first time this year.
