For now he's an excellent supporting player. He's got upside beyond that for future seasons, but his puck possession abilities are already impressive and he has the ability to anticipate where the puck is going and get his stick there. That speaks well of his potential as a future goal scorer. He's also way better than such a wet behind the ears kid should be defensively. He could stick in the NHL just for his defense and cycling and be a staple on someone's third line even if he never develops a scoring touch.
And there's no way this kid doesn't turn the skillset he has into at least a few 50 point seasons. That's the floor, the ceiling is higher.
He reminds me a little bit of a young Patrice Bergeron if I'm being honest. A bit too unseasoned to be a huge scoring threat -- yet. The game will eventually slow down for him and then we'll really see what he's capable of. But even at this early date he's puck hungry and reading the play extremely well. Once his scoring catches up with the rest of his game he's going to be a monster.
Put it this way -- he just started skating at NHL speeds and he's already good enough to be a third line checking winger and should probably play on the second PK unit if he isn't already. Put him in a forechecking and possession role and he's ready right now to contribute as a pro skater. That's astonishing for the limited experience he has. Once he gets his timing down at this level, the sky's the limit.
