Does Catton remind you of ?? Steve Y??
His game at this point is exclusively as a rush player, but a brilliant one. He attacks the middle of the ice relentlessly. He handles the puck extremely well for dekes and puck protection. Excellent playmaker, vision, quick strike goal hands. Really fast hands. He's competitive and doesn't get pushed around. He'll hack & whack when he needs too, and not softly, and he is not afraid to get involved in scrums with hardy facewashes. He'll help defend teammates.
There's no physical game. If he is forced to the boards, he's really weak and can get pushed off the puck quite easily. He doesn't use his body well in small places instead prefering to use his stick almost exclusively for poke checking. He doesn't do well in tight checking games, or with intense back pressure largely due to lack of strength.
Like most juniors, his defensive commitment waivers from shift to shift, as he's always looking for fast breaks. He'll also sometimes takes the longest route possible to come back to his own zone hoping for a quick transition strike the other way.
He desperately needs to gain strength. I don't see him as a center at next level. He's going to be a winger.
He's interesting in that while he has no physical/board game to speak of, he has an intense inside game. Everything is about attacking the middle of the ice. Most players who avoid physical contact are perimeter players. He isn't a perimeter player.
His comparable is Drouin -> Keller -> Marner.
