PASADENA, Calif. — Running backs Sony Michel and Nick Chubb arrived together at the University of Georgia. They have roomed together, bowled together, gone tubing together and thrown darts together. Just over a year ago, they arrived together once more — at a decision to fulfill their college eligibility rather than declare for the N.F.L. draft.

On Monday, the pair had the most dominant performance of their collegiate careers, colluding for 326 rushing yards and six touchdowns (one receiving) as the No. 3 Bulldogs hauled down No. 2 Oklahoma to win the Rose Bowl, 54-48, after two overtimes in the first national semifinal.

The outcome set Georgia (13-1) up with a de facto home game in Atlanta on Jan. 8 for the title against No. 4 Alabama, which defeated No. 1 Clemson, 24-6, in the Sugar Bowl later Monday.

Michel, whose mother immigrated from Haiti on an overcrowded boat before he was born, ran for 181 yards and scored four times — the final touchdown coming on a 27-yard run on the game’s last play. Chubb scored twice and gained 145 yards on the ground. Chubb ranks second and Michel third on the list of Georgia’s career rushing leaders, behind the Heisman Trophy winner Herschel Walker.
