Martone is a fluid skater in a short area, he needs to work on speed, as does Michkov.
Solokovskii is a good skater period, a lot of big guys look a bit awkward, Morin was straight line fast but not that good skating laterally. Solokovskill is a more fluid skater than I expected, easily changes direction and looks comfortable skating backwards.
He really is a freak, 6'7 238 and he has yet to turn 18, and doesn't look like a "giraffe," a young guy still trying to develop body control after his growth spurt. For a lot of big guys, this doesn't come until they fill out at 20-21. And you can see where that skating can make him special on defense, with his size and reach, the ability to smoothly position yourself and skate with your head up makes you very hard to skate around. And he has the mean streak that makes a big man more effective, he doesn't like to get beat and will use his big body to lay the lumber.
