The Whitecaps are affiliated with the MN Wild. So 3/5 teams are now affiliated with NHL teams.
Metropolitan Riveters - NJ Devils
MN Whitecaps- MN Wild
Buffalo Beauts- owned by Sabres ownership group.
Left unaffiliated as of now:
CT Whale
Boston Pride. The Bruins are the obvious potential NHL affiliate here, but they are in a tough spot, as the CWHL Boston Blades are also in town, so they may not want to choose one league over the other and have that be the league and/or team that folds. I doubt a team with an NHL affiliate would fold, so the concern is probably more about the league.
The lone team with a real issue is the CT Whale. The Isles & Rangers are both relatively close, although not that close. Also their colors are kind of tough to change at this point. They went with Hartford Whalers colors, which is a great scheme. Obviously an NHL affiliation likely means a color change. The Riveters have gone with red jerseys since the Devils affiliation, where they used to use navy blue. Although I just realized I don't think the Beauts are changing to match the Sabres, so maybe this is overthought.
I still think the NWHL & CWHL merging are the way to go and hope to see it happen down the road. The CWHL teams mostly have fairly obvious affiliation potentials: Calgary, Toronto, Montreal. They also have a team in Markham (?) and a new team in China! Okay, so those are much tougher to pair with.
