I think that some of us who've been saying this are simply being ignored. For example, check most of my posts on this thread.Biggest myth that people believe on this board right now:
That the NHL will give any consideration whatsoever to balanced conferences when relocating or expanding.
...It's a non-factor.
First consideration is simple: MONEY. Does a team in Seattle, Quebec, or anywhere else generate more money for the LEAGUE, which in turn will trickle down to the teams.
Second consideration is also simple: POLITICS. Balsillie couldn't buy his way into the boys club. There's a chance that some potential host cities may ruffle the feathers of others *cough* GTA *cough*.
There really aren't any other considerations. Realignment can be put into both the above categories, but unless realignment causes a major upset in the balance of the money or the politics, it's a moot point.
