He wins the pucks in the corners with his speed and ability to
'squeeze by' Defenders, plus he just looks more determined and puts in a lot of intensity when around the puck.
Perimeter player or not, but he is not afraid at all to attack the net. If a good pass is not available he will drive to the net by beating the Defender 1-1, or take him on the outside and cut inside <- IMO classical russian winger approach. You won't see him dumping the puck in unless its a line change or something.
His strongest assets I think are vision, passing, ability to create and finish plays.
Oh and don't forget his lethal slapper from the point, he netted quiet a few of them this year.
