MORGANTOWN, W.Va. (AP) - As much fun as No. 8 West Virginia's offense had in its Big 12 debut, the Mountaineers have to put all that behind with two road challenges ahead.

Their defense must look for ways to improve - fast - with games looming against two more unbeatens, at No. 11 Texas next Saturday and at Texas Tech on Oct. 13.

Records toppled while Twitter accounts and message boards lit up after the Mountaineers beat Baylor 70-63 on Saturday in the highest-scoring game in Big 12 history.

While West Virginia's offense amassed a school-record 807 yards, the defense gave up 700. The Mountaineers (4-0, 1-0 Big 12) have allowed opposing quarterbacks to throw for 300 or more yards in three of four games.
