The NHL decided to realign this season for a couple of primary reasons.
When the Atlanta Thrashers decided that they could no longer make a go of it on Peachtree Street, they moved from the deep South to the Canadian hinterlands and became the Winnipeg Jets.
That team spent two years in the Eastern Conference, but had no geographical business playing there. At the same time, the Detroit Red Wings and Columbus Blue Jackets continued to sing the blues about their Western Conference affiliations. Both teams wanted to move to the Eastern Conference, so the NHL swallowed hard and realigned.
