The Denver Post reports that Philadelphia and Chicago are the "clubhouse leaders" for Sundin's services this season, pending cap room. The Canucks are considered to be running third in this sweepstake.
Chicago would almost certainly have to trade one of their two big-money goalies to afford Sundin under their salary cap (Chicago currently is only about $2.6 million under), but they should be able to find a taker for either Cristobal Huet or Nik Khabibulin.
Philadelphia doesn’t have a lot of cap room either (about $4.5 million). GM Paul Holmgren is well respected around the league, and the Flyers have a good reputation with regard to taking care of players and treating them well.
