After Russia started the tournament with the big line of Miroshnichenko-Kvochko-Michkov, they soon split them up to spread around the offense. Not exactly sure the impetus for this, as they likely dominate the tournament either way. Part of it may have been the emergence of Demidov as the third line center convinced them they could have three highly dangerous line instead of just two. From what I saw looks like the most common lines were:
Perevalov - Kvochko - Michkov
Miroshnichenko - Gazizov - Rogovsky
Trikozov - Demidov - Sinyatkin
Lots to like about Perevalov's game. Looks like a smart 200 foot player; some pretty good skills but not sure just how high end. Miro with Gazizov was a much different look than I'm used to for Miro. Although he loves to shoot the puck, I tend to think of him more as a playmaker. Having an elite playmaker in Gazizov setting him up was a ton of fun to watch. Gazizov is just 5'10 but he's a solid body at 187. Not sure how high-end the overall skillset is, but that kid can make plays - elite vision and hockey sense. Sinyatkin is another interesting prospect; more of your traditional Russian winger - smallish, elite puck skills, but I'm not sure how much else.
After Slovakia had dominated everyone else in the tournament, they met their match and then some against Russia in the gold medal game. Huge dropoff in talent after the top six forwards for Slovakia, and a pretty big dropoff after the big three (Slafkovsky, Mesar, Dvorsky), who were spread between two lines. Slovakia's top two lines were largely able to keep up with any of Russia's lines, but their bottom six was victimized by by Russia's bottom six, and ultimately there's just no stopping Michkov and Miro.
The biggest surprise of the tournament for me was Jonathan Lekkerimaki for Sweden. I guess not a big shock, since looking at the stats going in he was a player I took note of, but there were two or three forwards I thought would be better. I thought he was probably Sweden's best player in the tournament. His speed and quickness alone make him dangerous, but his shot and hockey sense also look pretty high end. I'm still somewhat underwhelmed with Elias Salomonsson; I hear the hype, and I see flashes of brilliance, but most of the time he doesn't look like anything special. I guess to be fair he's a full 9 months younger than Mattias Havelid. I remember being somewhat underwhelmed with Luke Hughes at U17s when I first saw him too - was also the youngest defenseman on the team.
