Also, and this is just something I enjoy to follow because I would one day love to see every team have at least one championship in every major sport (probably ain't goign to happen in my lifetime), but there are now 18 teams with at least one cup and 12 teams w/o one.
18 who won - Pens, Flyers, Rangers, Isles, Devils, Canadiens, Leafs, Bruins, Hurricanes, Lightening, Blackhawks, Red Wings, Stars, Oilers, Flames, Kings, Avs, Ducks
12 who hasn't won - Senators, Sabres, Capitals, Panthers, Jets, Predators, Wild, Coyotes, Canucks, Sharks, Blues, Blue Jackets
You can class the Sens however you want, since their original incarnation won one, but I'm going by the current one.
The closest sport to having all of their teams win one is MLB, with 8 teams still needing to win one (stupid Texas Rangers last year).
