Their collaborative performance upstaged Oklahoma quarterback Baker Mayfield, this season’s Heisman winner, who was intermittently outstanding following a week of intense scrutiny over his dealing with flulike symptoms.

But as the game approached, he tried to dispel any notion that his energy remained sapped, dashing down the field just before kickoff while shouting and waving his arms to incite the Oklahoma side in the sea of red that made up the Rose Bowl crowd.

Georgia made hay of the Sooners’ stalled offense and eventually pulled in front by 38-31 with Jake Fromm’s 4-yard touchdown pass to Javon Wims — a short drive set up by Dominick Sanders’ interception of Mayfield.

Oklahoma finally found the end zone again with 8:47 left in the fourth quarter, as Mayfield ran and threw his team back into a tie on an 11-yard toss to Dimitri Flowers.

The Sooners took one more lead in regulation on a 46-yard fumble return by Steven Parker with just under 7 minutes remaining, but Chubb scored on a direct snap from 2 yards out with 55 seconds left to force overtime.
