Ok. This should be a fun exercise
Ohio State vs Michigan
Auburn vs Bama
Duke vs UNC
OU vs Texas
Army vs Navy
Kentucky vs Louisville (Basketball)
Overall I think it’s harder to include current pro sports unless you do it historically. The rivalries aren’t the same as when I grew up watching Bulls vs Pistons or Knicks vs Heat, Redskins vs Cowboys or 49ers vs Cowboys .
Red Sox vs Yankees
Lakers vs Celtics
Bears vs Packers
Giants vs Dodgers
Ohio State vs Michigan
Iron Bowl
Duke vs UNC
Maybe Steelers vs Ravens
I don’t follow hockey close enough to give an opinion, but the point of what I originally wrote is that Duke vs UNC basketball certainly belongs in the discussion of best college rivalries and given its excellence, longevity and how close the series has been for the past 40 + years it’s one of the best rivalries in all of sports .
I’m sure everyone will chime in on how this list sucks or whatever, but this is off the top of my head.
