Buie flourished in the second and fourth quarters at Texas.
The Jacksonville, Fla., native carried 11 times for 71 yards and caught two passes for 40 yards in the second quarter. The 111 combined yards accounted for 84 percent of the team's offensive production in that 15-minute period.
The fourth quarter was similar when the Mountaineers scored 14 unanswered points and pushed the lead to double figures with 1:18 left.
Buie had 100 of his career-high rushing yardage in the fourth quarter, and he carried the ball on seven plays of an eight-play, 76-yard scoring drive that made it 48-38 with 78 seconds left.
Buie rushed on the first three plays and the last four plays of that drive, which culminated with Buie's 5-yard touchdown run.
In the second and fourth quarters, WVU had 262 yards of offense. Buie had 213. He played a part in 14 of WVU's 26 first downs.
"We all think Buie's a good player," West Virginia offensive coordinator Shannon Dawson said. "He's young, so the more times we hand the ball to him he just gets better and better.
"The biggest thing, in my opinion, is that last drive when they know we're going to run the ball and he still kept breaking through. That guy, I don't know how much he weighs or whatever, but he always goes forward and he finishes runs forward.
"He's a powerful guy. That last drive was basically Buie and it won us the game."
With every pass, Smith resets multiple school records. With every reception, Austin and Bailey readjust some type of pass catching mark. The offense ranks No. 3 in yardage nationally, but the No. 64 rushing offense might have something else to flummox opponents.
"When you start getting a good pass rush, they've got a good counter punch in terms of running delays and draws and those type of things with him and also have good screens with him," Tuberville said of Buie.
"They do a good job of that."
