TSN analyst Darren Dreger just listed the eight teams still in the running for Kane: FLA, BUF, COL, DAL, DET, VGK, TOR, and NYR. It's going to be interesting to see what happens.
This is where the Canadiens and their nearly 5 million dollars of available cap space could play a role. For instance, the Toronto Maple Leafs might trade a bad contract and a first-round pick to the Montreal Canadiens to make room for signing Kane.
Update: According to Elliotte Friedman of Sportsnet, who reports on NHL Network, the top three teams among the eight favorites to sign Kane are the Florida Panthers, the Detroit Red Wings, and the Buffalo Sabres.
