All good points. He's a very smart, mature and driven kid. I have zero concerns that he's going to Daigle his way into the league and hope to stick on draft position alone. I expect that he'l be working with skill, strength and skating coaches as soon as the season ends, and given the strides (literally) that he's made this season, I'm really excited to see where he goes.
These same concerns -- size, strength, skating -- were raised about Heinola post-draft, and he responded by dominating Liga and the AHL and looking like an impact player already. I think the level of IQ that both he and Perfetti possess are a version of the Nik Ehlers speed/skating superpower. Took Ehlers a few years to reach his full potential as a PPG game-changer, but he has been a very important player for the Jets since well before that, and is now arguably our best player, along with Helle (and this season's version of Lowry), despite being too small, too fancy, too weak to protect the puck or defend or shoot well, etc.
Perfetti has a skill set that reminds me of a young Doug Gilmour, young Stats -- very cerebral players with excellent positioning, anticipation and puck skills who were able to see plays developing and stay several steps ahead of it, despite lacking speed and/or size. It may take a year or three for his body to catch up with his brain, but if he can stay on or near his present trajectory he's got the potential to be a key player for this team.
