From what I have heard, the talk is if you thought Bettman was nuts for as hard as he fought to keep Coyotes in Phoenix, he's even more entrenched in keeping the Florida teams where they are.
I've only been here in South Florida since 1998. When I first moved here, they still had Pavel Bure, and they weren't that bad. Bure was the big draw. I can remember going to games and the whole arena standing up when someone finally got him the puck while he was cherry picking at the red line. Once he moved on, they never replaced that "big star," which is something I think is a necessity in a non-traditional market. They thought Weiss/Horton were going to be their next superstars, but they never panned out that way. They thought Jokinen would help, but he also didn't pan out to that level. Luongo came along, but it was hard to get excited about having your top player as your goalie. Then Mike Keenan traded Luongo to Vancouver for Bertuzzi (hurt, played seven games), Bryan Allen (ok defenseman) and Alex Auld (career backup). That killed the fanbase.
After they finally got Alan Cohen to sell the team, the owners slowly started getting better. The county owns the arena, but the Panthers operate the arena, so they get income from non-hockey events. The suites in the arena are the largest arena suites in the country, it can seat almost 19,000, and is one of the better arena in the US.
Bringing in Dale Tallon has been the best thing for the franchise since the mid 90's. They have a lot of young talent up and coming in Huberdeau, Bjugstad, Markstrom, Barkov, Shore, Kulikov, and Gudbranson. Huberdeau is showing the promise of being that big name star the team needs. South Florida has so many transplants from other areas, it is hard for teams to have a solid fanbase. I think they will start being a constant playoff contender in another 2 years if their talent pans out.
I don't see them moving.
