Rykov is tricky.
I can get the argument, but he also played very limited minutes on a stacked SKA team. I think anywhere from 3-8 is reasonable. He will likely take a hit in these rankings due to the Russian factor and unfamiliarity with seeing him outside of the WJC, but I don't foresee him falling too far.
This is a prospect ranking, not a 'who is the best player right now' ranking.
I said it last year, but for these rankings, I personally like to predict what a player develops into and gage the usefulness of that role. Then I rank the prospects based on how useful I think that role would be on an NHL team.
So for Wood, I would say there's a decent chance he becomes a top-six forward, but more likely he becomes a bottom-six energy forward. I've yet to see any inkling of a cerebral approach to the game from him which limits his ceiling IMO. A guy like Blackwood who has the potential to be an all-star goalie but realistically projects as a leader in a tandem. I think I would value that more than an energy line forward.
Then again, I'm not very fond of what as a player.
