Levshunov likely would struggle anywhere as he looks very raw withou the puck but his offensive game is legit. Silayev looks ok with the puck but his lanky frame kind of makes it harder to gauge.
I saw him crush KHLers hard and box them off the puck with grace. Its really the speed and pace of the league that is hard to handle for a 17 year kid of his stature. As for the offensive side of his game, its harder to gauge, I would like to see him with his age group, but he skates well, has good hands and a good shot, so Im not too concerned. Sucks that Russia is still out from international competitons, well I fully agree with the IIHF decison, but on a hockey standpoint, Russia would have been pretty fun to watch at the WJC, Silayev, Simachev, Gulyayev on the back end, Demidov, Michkov. But, Miroschnichenko, Artamonov ect up front, Volokhin in net, ouf, thats a huge load of talent, they probably win gold.
Levshunov reminds me a bit of Mintyukov, I like his talent level, but as you say, a bit raw without the puck. The package remains attractive for sure, will go high.
