Lots of extraordinary games to choose from, as well as many ways to ascribe greatness: the size of the stage, the competitiveness of the game and the overall strangeness.
And we made the executive decision not to make this a list of USC upset losses -- other than the biggest one of those.
10. Oregon 56, Arizona State 55 (2 OT), 2000: Many of you are drawing a blank, but the ones who saw this one are jumping out of their chairs and going, "Oh man. That one was nuts." Both teams scored 21 points in the fourth quarter. The teams combined for 1,228 yards, 663 of those for the Sun Devils. Ducks quarterback Joey Harrington threw six -- SIX! -- touchdown passes, including three in the fourth quarter, the last of which tied the score with 27 seconds left after the Sun Devils gave away a critical fumble. Arizona State freshman QB Jeff Krohn threw five TD passes, by the way. ASU lost the game when coach Bruce Snyder decided to fake the extra point and go for the two-point conversion in the second overtime. It failed, leaving fans in Tempe stunned.
9. Washington State 30, USC 27 (OT), 2002: Any of you Cougars fans able to muster the memory of kicker Drew Dunning's slide on his knees at Martin Stadium? Dunning sent the game into overtime with a 35-yard field goal and then made the game-winner from the same distance in a victory that was critical to the Cougars' run to the Rose Bowl. The game featured a brilliant quarterback duel between Carson Palmer and Jason Gesser -- Gesser passed for 315 yards, Palmer for 381 -- and a dominant performance from Cougars defensive tackle Rien Long, who went on to win the Outland Trophy. Between this game and the 2006 Rose Bowl, USC lost just once.
8. Oregon 44, Arizona 41 (2 OT), 2009: If Arizona had won this game, we now know the Wildcats would have played in their first Rose Bowl. The Wildcats led 24-14 early in the fourth quarter, but then the game went crazy. With red-clad Arizona fans encircling the field, Ducks quarterback Jeremiah Masoli tied the game in regulation with six seconds left with a touchdown pass to Ed Dickson. Masoli then won it in the second overtime with a 1-yard run. Masoli ran for three TDs and passed for three more.
7. Stanford 24, USC 23, 2007: Greatest upset in Pac-10 history? Maybe. Stanford was a 41-point underdog playing its backup quarterback at No. 2 USC, which had won 35 in a row at home. But Trojans quarterback John David Booty, who foolishly played -- and was allowed to play -- with an injured throwing hand, threw four interceptions, while Stanford's Tavita Pritchard led a clutch, game-winning drive, throwing a 10-yard touchdown pass to Mark Bradford on fourth-and-goal with 49 seconds remaining.
6. Oregon 37, Oregon State 33, 2009: It was the Civil War for the Roses, with the Ducks earning a berth in the Rose Bowl after slipping a game crew of Beavers. While the return of Ducks running back LeGarrette Blount was significant -- he scored a critical touchdown -- the game belonged to redshirt freshman running back LaMichael James, who scored three touchdowns and rushed for 166 yards, and quarterback Jeremiah Masoli, who ran over Beavers safety Lance Mitchell to convert a fourth-and-3 play from the Beavers' 33 with 3:41 left as Oregon ran out the final six minutes with its final drive.
5. California 31, Oregon 24, 2007: Sixth-ranked California, featuring a stellar performance from receiver DeSean Jackson, outlasted No. 11 Oregon in a game between two teams that each would at one point rise to No. 2 during the season, though both ultimately crumbled. The game turned on a strange play as the Ducks were on the cusp of tying the score. With 22 seconds to go, Dennis Dixon found Cameron Colvin near the goal line, but Colvin fumbled trying to reach the ball into the end zone when he was hit by Marcus Ezeff. The loose ball went through the end zone and was ruled a touchback and possession for Cal.
4. Washington 33, Oregon State 30, 2000: It was the greatest game no one saw because of the late, West Coast kickoff at Husky Stadium. And at the time its magnitude wasn't clear. The critical play of the back-and-forth affair happened when Washington defensive tackle Larry Tripplett caught Ken Simonton for a three-yard loss on second-and-1 from the Huskies 26-yard line with 42 seconds left. The Beavers panicked and mistakenly spiked the ball -- they had a time out left -- and then Ryan Cesca missed a 46-yard field goal to tie. It was the Beavers only loss of the season; they crushed Notre Dame in the Fiesta Bowl. They would have played Oklahoma for the national title if they had prevailed. And the win helped the Huskies win the Rose Bowl tiebreaker.
3. USC 23, California 17, 2004: No. 7 California had a first-and-goal on top-ranked USC's 9-yard line with under two minutes left. At that point, Cal quarterback Aaron Rodgers had completed 29 of 31 for 267 yards and a touchdown. But the Bears couldn't punch it in, with USC registering a sack and forcing three incompletions. It was the closest call of the season for the best team of the USC dynasty.
2. USC 34, Notre Dame 31, 2005: The infamous "Bush Push" game. No. 9 Notre Dame was about to knock off top-ranked rival USC and make Irish coach Charlie Weis a national sensation, but Matt Leinart led a drive for the ages in the waning moments as the Trojans prevailed, scoring the winning points when Leinart got a little extra help from Bush on his second effort on a quarterback sneak.
1. Texas 41, USC 38, 2006 Rose Bowl: Perhaps the great game in college football history, particularly considering that the stakes were a national title for two unbeaten teams and the field was packed with talent and future high draft choices. Vince Young almost single-handedly willed his team to the victory -- he ran for 200 yards and passed for 267 more -- and denied the Trojans a third consecutive national title. USC walked away with a laundry list of "what ifs," but the ultimate result was a 34-game winning streak coming to an end.
