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.
