There aren't any Ovechkins, Crosbys or Malkins in this years draft....or anyone on Kovalchuks level either.
From what I've seen (albeit very little) Cherepanov could be similar to Semin - not in terms of style but impact. A 1st line winger who has the potential to be a top 15-20 point producer.
Don't count out wildcards like Esposito, Turris, Couture, Chrerepanov, and Kane. No one is really sure how good these guys can be. Each has shown tremendous promise but have a black mark or two as well.
Cherepanov - Dominating in the WJC and RSL like Malkin and Ovvy, but doesn't have their legs.
Esposito - Hasn't been a great year for the former consensus number 1, but still has a near flawless offensive arsenal. He may need some great coaching to bring it out.
Turris - Can create something out of nothing, but does it in the BCHL. I'd be more impressed if he were doing it in the dub.
Couture - All the talent in the world, but has been limited by mono and the recovery time. Still, has shown glimpses of a dominating forward.
Kane - small in size but huge in production. Does have some speed which has allowed smaller guys to succeed in the new NHL.
Now the likelyhood of one of them turning into a Crosby, Ovvy or Malkin is very slim. But there could be a Kovalchuk, Heatley, E. Staal level kid or two in that list.
And Cherepanov could easily be one of them.
