Doesn't seem right that Quebec has only one team, but Phoenix to Houston would be more likely. 4th largest metro in the US and a natural rivalry with Dallas all ready to go.
Otherwise an Eastern Conference team would have to be moved into the Western. The logical candidates, Detroit and Columbus are both relatively recent refugees from the West, so that seems unlikely. Bet on the status quo for the foreseeable future.
Back on topic ... My antipathy to Toronto is exceeded by my desire to see someone new hoist the Cup. Go Leafs (gag!).
