With No. 7 Michigan State and No. 3 Oregon looming, the Pac-12 blog got to thinking about other games of similar magnitude over the past decade.
After taking a look back, there's only a few others that -- when they were played -- match the pedigree of Saturday's game. Dating back to the 2004 season, there have been just four other games involving a pair of teams ranked in the AP top-10.
In that same time period, there was a total of 21 games between top-25 teams. USC was involved in the most (7), followed by Oregon (3), Stanford (3), Cal (2), Oregon State (2) one each for Arizona, Arizona State, UCLA and Washington.
In chronological order, here are 10 of the most anticipated nonconference games of the past 10 years. The criteria for inclusion was simple: both teams had to be ranked and there could only be one matchup between the same teams. The second part eliminated No. 9 Cal vs. No. 23 Tennessee in 2006, No. 3 USC vs. No. 8 Ohio State in 2009 and Stanford vs. Notre Dame in 2011 and 2013 -- all of which would have been great choices, but would also have made for a less interesting look back.
Half the winners from these games finished the regular season undefeated.
(*-denotes ESPN's "College GameDay" was at the game)
2005 -- No. 5 LSU 35, No. 15 Arizona State 31: In Les Miles' first game as the coach at LSU, future No. 1 pick JaMarcus Russell helped the Tigers erase a 10-point fourth-quarter deficit to win. LSU finished the year No. 6, while ASU fell out of the ranking for good in Week 6 after losing back-to-back games to No. 1 USC and No. 25 Oregon.
2005 -- No. 1 USC 34, No. 9 Notre Dame 31*: Remembered simply as the "Bush Push" game, USC quarterback Matt Leinart scored a game-winning touchdown in the final seconds thanks to a memorable shove from running back Reggie Bush. USC went undefeated the rest of the way until losing to Texas in the Rose Bowl; Notre Dame finished ranked No. 9.
2006 -- Oregon 34, No. 11 Oklahoma 33: Oregon QB Dennis Dixon scored a touchdown with 1:12 left, the Ducks recovered a controversial onside kick moments later and scored another quick touchdown take the lead. The game wasn't settled until Oregon blocked a 44-yard field-goal attempt as time expired. Oregon eventually fell from the rankings in Week 11 and Oklahoma finished the year ranked No. 11.
2007 -- No. 12 Cal 45, No. 15 Tennessee 31: A year after losing to the Vols in Knoxville, WR DeSean Jackson and RB Justin Forsett led Cal to a big win against Arian Foster and Tennessee in the season opener for both teams. Cal climbed as high as No. 2 in the rankings before finishing unranked and Tennessee finished No. 12.
2007 -- No. 1 USC 49, No. 14 Nebraska 31*: USC led 42-10 at one point and rushed for 313 yards as a team. Coincidentally, Nebraska Sam Keller was ASU's QB in the 2005 game against LSU. USC finished No. 3; Nebraska lost six of its final seven to finish 5-7.
2009 -- No. 14 Boise State 19, No. 16 Oregon 8: Chip Kelly's first game as the Oregon head coach was remembered mostly for LeGarrette Blount's postgame punch, but it also doubled as the first game in an undefeated season for Chris Petersen's Broncos. Both teams actually improved their rankings by the season's end: Oregon finished No. 13 and Boise State No. 4.
2010 -- No. 6 TCU 30, No. 24 Oregon State 21: A year after narrowly missing out on a berth in the Rose Bowl, Oregon State opened the year with a tough loss to Andy Dalton and the Horned Frogs in the second Cowboys Classic. TCU finished undefeated and ranked No. 3; Oregon State went 5-7.
2011 -- No. 4 LSU 40, No. 3 Oregon 27*: One of just two meetings between top-5 teams on this list, Oregon's mistakes proved costly against LSU in the third Cowboys Classic. LSU went on to play for the national title and finished ranked No. 2 and Oregon won the Pac-12 and finished No. 4.
2012 -- No. 7 Notre Dame 20, No. 17 Stanford 13*: As previously noted, any of the Stanford-Notre Dame games over the past three years would have qualified, but this one was played with the most on the line. If Stanford had won, the Cardinal would have finished the year a solid candidate to play for the national title. Instead, Notre Dame finished undefeated before losing that title game to Alabama. Stanford went on to win the Pac-12 and finished ranked No. 7.
