There is only one answer for the most universally respected player and that is Patrice Bergeron. I've never heard or read one bad thing said about him. By hardcore fans, casual fans, the media, other players, coaches, GMs, etc etc. The guy is everything you want in a hockey player. Plays both ends of the ice exceptionally well, is a leader and a mentor, does not whine or dive, treats media and fans respectfully, and has won everywhere he's been. Lots of people HATE the Bruins but wouldn't dare say something negative about him. Bergeron is the man.
