Sean Avery, New York Rangers: Even if this wasn't alphabetical, he's the top of the list. From his behavior on the ice as a preeminent pest to his legendary diss of his peers and former girlfriends, he craves the role and plays it better than anyone in hockey. He's also lobbied in the past that the NHL needs to market its villains; something we actually agree with.
...the longer Avery is at the top of this list, the longer he will be an effective player for the Rangers.
