The Tigers (4-0) converted two of the four turnovers they created into scores, built a big early lead and withstood West Virginia's strong comeback for its third win over a ranked opponent this season, with all of three coming away from home. Every win so far has been by double digits.
West Virginia (3-1) outgained LSU 533-366. Smith set school records for completions (38), attempts (65) and passing yards (463). But he was intercepted twice after throwing one in the previous three games.
And for the second straight year, the Mountaineers (3-1) couldn't overcome a double-digit halftime deficit to the Tigers.
"We got down early and we came out in the second half and fought to the end," Smith said. "We learned that if we don't shoot ourselves in the foot, we can pretty much play with anybody."
