islanders vs. Rangers
It came from the NHL rivalry between the Montreal Canadiens and the Boston Bruins.
Chare is by far the biggest player in the NHL
me and me
It is a known fact that the Bear's/ Packer's rivalry is the fiercest rivalry in the NFL, but I'm not sure about all of sports.
The Steelers Biggest Rivalry is with the Cowboys as they matched up as two dominant teams of the 90s and faced off in the Superbowl at one point.
The rivalry is still alive but I find that the Montreal - Boston rivalry is bigger
celtic - rangers Celtic Rangers is a huge rivalry I'll admit, but THE biggest rivalry in the world is the Derby Della Capitale, which is AS Roma (Roma) vs. SS Lazio (Lazio)
The biggest rivarly in the wwe is Randy Orton and The McMahons includes Triple H No the biggest rivalry in the history of the WWE was Stone Cold Steve Austin and The Rock NO,the biggest rivalry was when snitsky killed kanes baby all of these are good but not as brutal as triple h and Kevin Nash
Real Madrid and Barcelona
Yes i think
Argentina vs. Brazil.
That changes on a weekly basis.
