STANFORD—Toby Gerhart turned what could be Charlie Weis’ final game as Notre Dame coach into his own Heisman Trophy infomercial.Gerhart ran for 205 yards and three scores, threw an 18-yard touchdown pass and scored the game-winning touchdown with 59 seconds left to help Stanford hand Weis and the Fighting Irish a fourth straight loss to end the regular season, 45-38 Saturday night.On a night when Jimmy Clausen and Golden Tate put on an aerial show for the Irish (6-6) in a showcase for Weis’ offense, it was Gerhart who won the game for Stanford (8-4) and possibly earned a trip to New York as a Heisman Trophy finalist in two weeks.He threw his touchdown pass to Ryan Whalen on fourth-and-4 to help the Cardinal tie the game early in the fourth quarter and then won it with his 4-yard run in the final minute.
