The sky is falling, the sky is falling... LOL
These predictions are always hard in the off season, before teams make moves, reshape their rosters potentially for years to come.
Ottawa and Montreal made decent steps last year. We shall see what they do in off season acquisitions, to continue to improve their team. If Tkachuk goes south to play for his brother, will Ottawa continue it's path? Montreal has a few areas to improve, but I think they'll be the better of the two teams before long.
Detroit and Buffalo are neither good enough to really step forward, or bad enough to get the quality they need. Buffalo doesn't seem to be able to develop anyone, their management has been a disaster, and almost everyone who leaves, ends up better after doing so. A good management strategy, is probably grab an underperforming player from Buffalo. 9th OA isn't going to help them. Detroit is caught in that... not bad enough to draft well, not good enough to do anything...
Boston is done for now. It could take them a few years to really rebuild that team. Pastrak is still Pastaman, but he can't do it alone... and he's alone there.
Tampa is going to hang in there for now... probably be a 2/3 seed, but I don't think they'll be good enough to break through.
Florida... depends on their off season. I'd bet the bring Bennett and Ekblad back, and continue to qualify for the playoffs, not try too hard, and then be strong in the playoffs. They have a deep group, and it's an attractive destination to play.
Toronto - Well, that's up to Tre at this point.... Who knows.. easy playoff team, might never be a competitive playoff team
