All I can say for sure is where I would personally rank Chernyshov.
Looking at the 16 rankings used in the player pages at eliteprospects.com, Chernyshov's consensus ranking is in the low 20s. He has 1 top 10 ranking (#10, Dobber) and two top 15 rankings (#13 THN Kennedy and #14 THN Ferrari -- who probably discuss prospects together often, much like myself and
@Guadana have done in the past).
Chernyshov's low rankings are #28 by DraftProspects and #30 by McKeen's.
I'm not sure where the analytic lemmings like Bader have Chernyshov, but since he played mostly in the KHL in a checking role, I'm guessing he might not even be considered a 1st round pick by them.
It's impossible to say for sure of course, but I'm guessing if Chernyshov played in the CHL he'd have at least a comparable stat line to a guy like Liam Greentree (36-54-90).
Greentree is a power forward like Chernyshov, a wing like Chernyshov, who plays a similar type game at about the same size.
Comparing the two players, I would say Greentree certainly has the better shot, and I would also give him a slight edge in passing vision. Conversely, Chernyshov has an absolutely huge edge in skating, is the better puck handler, is better defensively and on the forecheck, is a better skater, has a slight edge in IQ and is the more competitive player in general.
None of this is a slight on Greentree, who is a very good prospect whom I really like, but then we take a look at his consensus rankings: as high as #6 overall (Smaht Scouting) with an additional #9 (THN Ferrari), and just one ranking outside the top 20 (#21, Sportsnet). Greentree's consensus ranking is probably in the #13-#14 range.
My question would obviously be -- what makes Greentree a better overall prospect than Chernyshov? I'm not sure but the difference is significant -- probably about 8 or 9 spots in the consensus favoring Greentree.
Ultimately, we all have different criteria when assessing hockey prospects. My top 3 are skating, IQ and compete level, all three of which favor Chernyshov over Greentree. If someone gave more weight to shooting and passing creativity for wingers, I'd guess it would be close to a dead heat between these two. But ranking Greentree at #6 and Chernyshov in the 20s simply makes no sense to me unless you haven't really watched much of Chernyshov.
Anyway, it's interesting to think about, but I can't give you a straight, confident answer. Personally, I have Chernyshov in my top 10 and Greentree will probably be in my mid-1st round range. They are both terrific young talents. But for my taste, Chernyshov's rare mix of power, smarts, skill and speed make him an extremely exciting and rare prospect.
