Geno Smith threw for 323 yards and four touchdowns and added another score on the ground, as the 11th-ranked West Virginia Mountaineers started the season with a 69-34 rout of the Marshall Thundering Herd.
Smith completed 32-of-36 passes and carried the ball eight times for 65 yards for the Mountaineers (1-0), who racked up 655 yards of total offense. Paul Millard also threw a touchdown pass.
Shawne Alston carried the ball 16 times for 123 yards and two touchdowns for West Virginia, which played its first game as a member of the Big 12 Conference. Stedman Bailey led the receiving corps with nine catches for 104 yards and two scores.
Rakeem Cato connected on 38-of-54 passes for 413 yards, two touchdowns and an interception for the Thundering Herd (0-1). Travon Van carried the ball 16 times for 38 yards and two scores.
The Mountaineers scored a touchdown on their first offensive possession and never looked back. Alston's nine-yard run combined with a 15-yard personal foul on Marshall set up West Virginia at the 33. Two plays later, Smith rolled to his right and found Bailey in the end zone for a 32-yard score. Tyler Bitancurt missed the extra point.
West Virginia made it a 13-0 contest on its next drive. J.D. Woods caught passes of 22 and 11 yards to put the ball at the Marshall 6-yard line. Alston capped the eight-play march with a three-yard TD run.
After forcing another punt from the Thundering Herd, the Mountaineers marched down the field again. The home team decided to go for it on 4th-and-goal from the 3-yard line. But Smith was stopped on a quarterback sneak with seven seconds left in the first stanza.
Marshall's offense fed off the stop and put together a 14-play, 98-yard scoring drive. On 3rd-and-7, Eric Frohnapfel caught a 24-yard pass to get the ball past midfield. Van's 16-yard run and Aaron Dobson's 12-yard catch preceded Van's four-yard TD run, which cut the gap to 13-7.
But it was all West Virginia from that point on. Smith completed three straight passes before Andrew Buie rushed for 18 and 24 yards, with the latter resulting in a score.
After Justin Haig made a 34-yard field goal to make it 20-10, Tavon Austin caught a six-yard TD pass from Smith. Austin started the three-play drive with a 70-yard run.
Woods caught a nine-yard TD pass with one minute left before the half, making it a 34-10 contest.
Alston and Smith recorded rushing touchdowns around Van's three-yard TD run in the third period. Isaiah Bruce returned a fumble 43 yards for a score and Haig made a 29-yard field goal to cap the scoring in the frame.
In the fourth, Bailey and K.J. Myers scored for the Mountaineers to make it a 69-20 game. Tommy Shuler and Frohnapfel caught TD passes for Marshall to account for the final margin.
