Courtney Martinez | NCAA.com | November 26, 2015 Rivalry games dominate college football in Week 13 Share Believe it or not, the college football season is already starting to wind down. But there's no better way to end the regular season than rivalry week. These games have plenty of implications not only on the conference titles but the national playoff picture as well. One of the more intriguing rivalry games is the clash between No. 6 Notre Dame and No. 9 Stanford. The series dates back to 1925 when Knute Rockne's Irish and Four Horsemen went up against Pop Warner and Ernie Nevers in the Rose Bowl. The two teams have met every season since since 1988 except in 1995 and 1996. Here's what to watch for in the 2015 edition between the top-10 teams and other rivalry storylines to look for in Week 13. Other stories to watch The Return to Jordan Hare... While Auburn is having a down year and Alabama is a playoff contender, crazy things have been known to happen in the Iron Bowl. There's no need to remind fans of the last time Alabama and Auburn met in Jordan Hare. The Tigers may not be in the hunt for the SEC West division, but a rivalry game is never a safe bet. It all comes down to Bedlam... Once again, the match up between the Sooners and Cowboys will help decide the Big 12. Oklahoma clinches the conference with the win and possibly a playoff spot with its resume. Oklahoma State needs a win to stay alive in the conference and hope that Baylor loses to TCU or Texas in the final two games. The Cowboys won their only title thanks to a win in 2011 and almost won another two years ago. Harbaugh-Meyer showdown... To say Michigan fans have waited all season for the Ohio State game is a total understatement. While the players certainly are familiar with each other, it's the first time Jim Harbaugh and Urban Meyer face off on the sidelines against each other in the rivalry. A win is important for either team but only for bragging rights unless Penn State pulls off the upset against Michigan State.
