Looks like this conversation has gone a bit off the rails. Ends up being two extremes babbling at one another, and everyone else staying far away. Reminds me of an internet political discussion.
Way I see things, Slafkovsky's potential hasn't changed much from where it was at the start of the year. He's got excellent size, skates well, has great skill and a good shot. His assets are undeniable (and plentiful), but he has yet to put them all together for a full season. This year is a mixed bag, because his numbers weren't great and his progression was very up-and-down, with a slight upward tick, but nothing crazy. Thing is, he still has all the tools to be the best player of this draft class, but he also still has a lot to prove. Yes, he struggled in the NHL, but at the same time, Cooley, Jiricek, etc didn't exactly PLAY in the NHL, so it's hard to make one-for-one comparisons.
If we're all being honest, we know he is not a #1 pick in a normal year. He is also not the type of player that comes into the NHL and instantly dominates. We all know he will take some time to actually show what he can do at his best. If you're making grand proclamations and definitive statements about this guy's future after 30 NHL games, good or bad, you're a fool. Prospect development is a patient man's game, and only in a number of years will we truly know what Slafkovsky is capable of. I remain optimistic.
