There was a seismic event in the Bay Area this weekend … and it had nothing to do with earthquakes.

Stanford and Oregon, the two teams which have won all five of the Pac-12 titles to date, officially bowed out of the race for the 2016 Pac-12 championship. On Friday night, Oregon lost to California, 52-49, in a game which featured 203 plays, 101 points, and 1,086 total yards. Then, on Saturday afternoon, Stanford lost to Colorado, 10-5, in a game which featured a grand total of one touchdown and just over 600 total yards between the two offenses.

Oregon and Stanford found two different ways to lose this weekend.

Yet the two teams suffered similar fates.

Oregon, which has lost five straight for the first time since 1996, fell to 2-5, 1-4 in Pac-12 play. Stanford, which lost to Colorado for the first time since 1990, fell to 4-3, 2-3 in Pac-12 play. While there are still mathematical possibilities for the Ducks or Cardinal to overtake Washington (7-0, 4-0) and Washington State (5-2, 4-0) … it ain’t happenin’.

Which means that, after three Stanford titles (2012, 2013, and 2015) and two for Oregon (2011, 2014), there will be a new Pac-12 champion anointed at the Pac-12 title game in Levi’s Stadium on December 2nd.

A changing of the guard.
