Note to Preds fans: I don't necessarily want to see the Preds move to Hamilton because I think they have a very solid base of real fans who deserve a better fate, and because their rivalry with the Blues has been intense in the past few years.
However, if they do move, there will be an imbalance in the league and it will probably lead to the addition to 2 new teams in the west. In my uninformed opinion, Las Vegas- because no other league has had the guts to go there and Winnipeg- because they deserve to get a team back, would be the best places to expand.
Here is my realignment idea for the 32 team NHL:
The only team really out of place geographically is Minnesota, but the natural rivalry with the Stars would make it work.
edit: I failed to mention the best part of a 32 team league- the schedule.
Teams would play 6 games vs divisional rivals (6x3=18)
Teams would play 4 games vs conference rivals (4x12=48)
Teams would play 1 game vs ALL teams in other conference (1x16=16)
I would keep the PO structure the sam with the divisional winners getting the top 4 seeds and the best of the rest getting 5-8 in each conference.
Also, since Flyers fans seem very adament about staying with the Rangers and Devils, I have swapped them with the Sabres.
