Florida was legitimately good last year and was up there with the likes of Pittsburgh, Philly, Minnesota, Anaheim, Nashville and Winnipeg one of the hottest teams during the 2nd half of the season. They have a legit as **** offense and defense and Luongo is still pretty good (They make it in over the Devils and finish ahead of CBJ for the 1st WC if Luongo doesn't get hurt.) They finished 19 points ahead of us. They're flat out better than we are. This isn't even up for debate.
Philly too, plus they added JVR. Injuries aside I don't see how you can peg them for a decline. they have a good young D and Giroux/Voracek are better than anything we have on offense (their depth is better too).
Devils will regress, but not to the point where they're worse than us. If Hall misses significant time next year, we can have this discussion. CBJ too if Panarin gets traded but that isn't a given. If he stays and they have that cloud hanging over them, I doubt it will be much of a distraction.
I think it's fair to group the Rangers in with the rest of those teams, but lets say everything went right for all of those teams (OTT, MTL, DET, NYR, NYI, CAR,BUF) the Rangers aren't finishing at the top of that group. Now everything won't go right for any of those teams, but the less things you need to break in your favor, they better you normally are.
I even struggle to put Carolina there, they've clearly improved. Buffalo has enough pieces to be one of those teams that takes a quantum leap but I can't comfortably make that prediction.
