My top five cities for expansion/relocation:
1. Seattle
2. Quebec
3. Houston
4. Madison/Milwaukee
5. Las Vegas
Here's my issues with those:
1. KeyArena was vacated since the Sonics couldn't get renovations or a new arena, and sold to OKC. KeyArena currently operates on its own budget without public funds, so that will likely continue until they aren't making a profit anymore.
2. Arena under construction, and Quebecor is on the bandwagon, but no traction as far as relocation yet. Phoenix will drag for another year, and the Islanders under Wang will be playing out the lease at the Mausoleum until 2015. After that, unknown.
3. The 4th Largest city in the US only gained 6,326 per game this year at the Toyota Center (same as the Rockets, 17,800 capacity for hockey) and a paltry 5,623 per playoff game (and they lost in the finals!)
4. Milwaukee before Madison, since Madison is a college town. Who would be the owner? AHL puts the 17,845 seat Bradley Center with 5,796 season, 3,563 Playoffs, not a good litmus. Plus, what kind of corporate support would there be?
5. Jerry Bruckheimer has talked before about moving a team to vegas, since he has money and loves hockey. Arena? Thomas and Mack center is pretty big, but is on the campus of UNLV.
There WAS a consortium out of Tulsa, OK that was thinking about getting the Penguins a couple years ago, dunno if that could flare up again. Portland OR has been tossed about, but that all depends on Paul Allen since he owns the Rose Garden.
