(i'll just repost what i composed in the around the league thread...)
realignment was so common in the 70s and 80s and even early 90s that this kind of restructuring is long overdue...the time zones finally make logical sense, detroit and columbus belong in the east, and it gives some fresh divisional rivalries
however after a few years i can foresee major complaints about inequity in playoff seeding, especially from the eastern teams, which is essentially why the 4 conferences got broken down into 6 divisions in the first place
expansion will also be interesting...do detroit and columbus simply rejoin the west if new franchises get input into quebec city or toronto?
