Well I know a few rivalies some of them you may not of heard of, since I am not really a pro sports fan, but semi-pro hockey and college football I love. College football WVU Mountaineers and University of Pittsburg Panthers, Ohio Buckeyes and Michigan Wolverines, Texas Longhorns and Oklahoma Sooners, Texas Longhorns and Texas A&M Aggies, UTEP Miners and NMSU Aggies, NMSU Aggies and UNM Lobos, and a few others I forget at the moment. Now ECHL Hockey there is only one rivalry I got to see that was heated and that was the Alaska Aces and the Victoria Salmon Kings. I saw about 5 fights in about 5 minutes, God it was a great first hockey match to take in.
