I expect Suzuki and Caufield to do well too. I think they are good young players. I do not think they are superstars though. Suzuki, at best, is Bergeron-lite. Caufield could be a 35-goal scorer, sure, but he is not the straw that stirs the drink type of player.
The other teams the Habs will be competing against all have better top talent than they do. Florida (Huberdeau, Barkov, Ekblad), Tampa Bay (Kucherov, Point, Vasi, Hedman), Toronto (Matthews, Marner), Boston (Bergeron, Marchand, Pastrnak) and even Ottawa (Stutzle, Chabot, Tkachuk).
And that's only their division. Carolina (Svechnikov, Aho, Slavin), Washington (Backstrom, Ovechkin, Carlson), Pittsburgh (Crosby, Malkin, Guentzel, Letang), Islanders (Barzal), Rangers (Panarin, Fox and their young talent has more potential than the Habs'). Add Philadelphia who is likely going to be in the mix as well.
In their division, I think they will finish 4th at best. 5th is my prediction and I would not be surprised if they finished 6th. So, if they finish 4th, they need to be better than 2 of the teams I have fighting for playoff spots in the metro. If they finish 5th, which is the likeliest scenario in my opinion, they'd need to do better than 3 of the 6 to make the playoffs.
My prediction would be:
1. Tampa
2. Florida
3. Toronto
4. Boston
5. Montreal
6. Ottawa
7. Detroit
8. Buffalo
I mean, I won't argue too much about your "they objectively finished second" stance, but do not forget that they finished the regular season 18th while playing in a SHIT division. They had a great playoff run, sure, but that does not make them a better team for THIS season. They finished 24th the year prior. The larger sample size is much more indicative of their real worth. You think 34-years-old Price will return to 2015 form and sustain his playoff performance for an 82-game season? I certainly hope so for you, but I would not count on it. Their depth is nice, but the top of the roster is very poor. They'll be competitive, but not a serious contender. One fluke run under very particular circumstances does not change that and is not indicative of their potential. In a normal year, they would not even have made the playoffs and if they did, they would have been Bolts fodder by the second round at best.
So, I admire your optimism, but, objectively speaking, the Habs are a long shot to make the playoffs. They'll compete for a spot, but I would not favor them for one. Having them finishing 2nd is borderline lunacy, not a "high bar". That would require them to overperform 3 of 4 clearly better teams. I think they can beat Boston and finish 4th, but that's the high bar for that team, IMO. It is the definition of a mediocre team. Lots of depth, no top talent, entirely dependent on their goalie. If I had to give a probability of them making the playoffs, I'd say 25% at best.
