Atlantic is tough to predict but if you were to pick 4 I'd be picking today between TB, FLA, TOR, BOS and Ottawa, maybe Detroit depending on how this day finishes.
TB, FLA and TOR all got slightly worse
Bos may be staying the same with Krejci coming back
Det and Ott are looking to take a step forward
Buffalo is brimming with talent that it may boil over soon
MTL is likely to have another tough year while waiting for Berg's brutal contracts to expire (Byron, Drouin, and Dadonov along with Allen).
Edit also think today cements MTL as a bottom 5 team next year, too much talent in the division on the other teams
