The crowds in Phoenix have been pitiful - and don't seem likely to improve. They seem to have almost as many away supporters as home.
They need success to bring in the crowds, but can't afford success without the crowds. This season, they have a good young team, we will only get better (IMHO) unless they trade away all the best players. They should have made the playoffs, if it wasn't for that nose dive after the All Star break.
Ontario would be a better bet - you would guess that there is a much bigger market for NHL hockey there, more than Phoenix anyway.
