He's easily worthy of the conversation for many reasons.
#1. Lots of nickname potential.
#2. We don't have a D like him, not close.
Watching his games then watching highlights is a refreshing thing. Point is, his highlight reel stuff is full of elite plays but he's not off the leash trying something crazy every shift like kids in juniors with fancy highlights. Most shifts he's downright conservative if not unremarkable. He chooses when to turn on the jets very wisely and when he does? Watch out, crazy dangerous. The guy looks like a legit forward against young adults when he gets the chance to cycle and make plays but he's also very respectable in his own zone already. And, he has a few power forward type moves too, once in a while he'll drive the net with one hand on the stick as the other guy gets a full Heisman Buium pulls a sweet finish.
Point is....His playmaking & offensive gifts don't come at the expense of being a wasteful player. While +/- is oft flawed, he led his team in the + column regardless. And, given his age against the NCAA he's already much stronger on the puck than you'd expect, or as one announcer put it "he does things you just don't see here from 18 year olds."
Dude could be a gamer?
I hate saying "could be" because at 2nd overall after a **** season you wish we'd have a 90% consensus lock down at that pick. But here we are.
If his game could translate to the NHL? You have a completely different type of threat on the back end, not a D with some scoring touch but a D that could on a dime completely burn a team offensively when he sees a seam. That changes a team's dynamic and tilts the ice.
