Last night I heard an ESPN commentator say the Ohio State vs Michigan rivalry was the premiere rivalry in sports. I would beg to differ.

So In your opinion what are the best rivalries?

College:
Auburn vs Alabama:
No offense to anyone but the passion of Auburn vs Alabama cannot be touched. If you live in the south you know this is true. I have zero rooting intrest in either team but I can see the obvious.

Pro:
Red Sox vs Yankees:
As much as I love the NFL and probably would have siad Bears vs Packers years ago, the Yankees Sox war has overtaken any NFL rivalry IMO.
