So I was watching a special last night on the Jerry Buss (Lakers Owner)passing, and it was mentioned that the Lakers-Celtic games have been the biggest rivalry in the NBA for a long time. Which then made me think about baseball, you have the Red Sox-Yankees that goes back as far as baseball and continues today. So what is the equivalent in the NFL? Is there a matchup that would get put in the catagory of those two rivalries? I can think Raiders-Chiefs, Cowboys-Skins, Bears-Packers but even those to me dont have the same feeling as the NBA and MLB rivalries. Thoughts?
