Last week is very hard to beat.
Bobby Bowden at halftime going "it's like we don't know who to tackle" comes to mind, but the problem with picking any games from the CPJ era is he was usually winning by scoring every time he got the ball - defense was rarely a strong suit and he never did find the right defensive coordinator.
All that being said, I think the Orange Bowl win is the contender. Cam Ward *might* win the Heisman, but Dak Prescott has played on Sundays for many years, and Miss St was the best team in the SECW in 2014. And we didn't just win, we won convincingly. Unlike many of Chan's best games, you couldn't hang this 2014 win on one super-special player. Total team game.
