I know and watched him just like you. Safe range is 50-70 pts and I stand firm on that. He's on a good track but none of us know where he maxes out at.
Where Slafkovsky maxes out will depend on the skilled depth that lines up behind him on the team roster. The same goes for Suzuki and Caufield, even if Suzuki has shown consistent growth despite an injury plagued team that hasn't provided a genuine 2nd line long term to support him in the last few years.
Without a top-9 that can score more than we have seen lately, the Canfield - Suzuki - Slafkovsky line will be good, but won't be great.
Montreal needs some luck on the injury front (Dach and Newhook) and needs to inject some real offensive talent (without sacrificing too much D) up front.
Before that translates into the actual NHL lineup, we are still couple of years away, at best, short of seeing some cracklin' for Macklin later tonight.
Hopefully,Hughes adds at least one element at a time and we see a 2nd line of, barring winning the Celebrini lottery:
Newhook - Dach - Hughes Acquisition (however it is done)
-OR-
Hughes Acquisition (however it is done - Dach - Roy
as a second line to support Suzuki's line.
I prefer developing Roy with Dach and an NHL-level acquisition that can have an immediate impact because new hook would help pivot a quality 3rd line for a healthy top-9at the same time.
IMO, Montreal does not have an elite top line, or top-6 in the making (yet) tone a two-line offensive team. We will need to rely on the scoring depth of our top-9 and the strength of our future D-Corps to make headway in the playoffs, eventually.
