Sidney Crosby vs. Alexander Ovechkin
The NHL's two most-recent MVPs have been rivals for four years, not just on the ice, but in the media too. With fans increasingly engaged in the rivalry, the players make no attempt to hide their mutual dislike. Crosby has bristled at Ovechkin's goal celebrations: ''Some people like it, some people don't. Personally, I don't like it.'' Meanwhile, when asked to assess Crosby's style of play, Ovechkin said: ''He is a good player, but he talks too much.'' With pushing, shoving, and a ''bye-bye'' wave from Ovechkin, the rivalry won't cool off any time soon.
