Masterful drive by USC's Barkley, McKnight

Posted by ESPN.com's Adam Rittenberg

COLUMBUS, Ohio -- Matt Barkley and Joe McKnight just made a record crowd of 106,033 at Ohio Stadium go silent.

The USC freshman quarterback and his junior tailback just went 86 yards on 14 plays, draining 6:10 in the process to give their team its first lead since the first quarter. Barkley was masterful, converting a fourth-down quarterback sneak for the third time in the game. The Trojans finally overcame their horrendous field position and made the big plays when it matters.

Barkley will undoubtedly get much of the credit, but McKnight's play really spurred the offense.
