Between the fans no doubt. But I don't think the players really care. They are just doing their job and getting paid a lot of money to do it.

I think what I was getting at more than just "are rivalries dead" is, will fan rivalries continue if the players don't care? If the Yankees and Red Sox players in the old days didn't care like the players today would there be a big rivalry today?

And will newer teams like, in baseball, the Rockies, Marlins, Diamondbacks, Rays... will they ever have a die-hard fan rivalry with another team? I don't think so because the players aren't showing the emotion to fuel the fans that love them.
