There are youtube channels that post all players shifts in a game. It lets you see their whole game not just see their best plays. I watched one game of IMO the four most interesting prospects, making me an expert, and no one close to McKenna.
Mckenna is just special. He is so smart and he has all the skills to play at the speed his brain is processing at. Never mind the draft, the way he sees the ice and controls the pace to manipulate the D is something most NHLers can't do. The only reasons he wouldn't go first is that it took him half a season to adjust to the NCAA. But he adjusted. From a production standpoint there aren't many close in all drafts combined. You can shit on his effort off puck, but he's just doing what has worked for him. He's backchecking hard in the third period of blowout games. His game will evolve in the NHL, just like it did moving up to the NCAA.
Stenberg is a really good player. He's also really smart, but the skill level is nowhere close. He's a high hockey IQ grinder (thats small and average speed). His xG number must be very good. He's a winger version of Aho. Very good player that any team would gladly take, but all Carolina has wanted for years is a guy like McKenna.
Chase Reid is awesome. His eye test is unreal. He's the best skater of all the top guys by a lot. He also controls the pace of play because he is so good without the puck. He just kills plays and the puck is going the other way. He's big, he is physical one on one. He's like a Jake Sanderson/Drew Doughty type. I don't think he'll score like Makar/Hughes, but he's a stud. If Mckenna was closer to a Hughes type maybe you take him 1. If he was a Hischer, Slafkovsky of course. But not over a McKenna. I would take him 2 in a heartbeat.
Carels production is elite. Amazing passer with a big shot though. He has higher offensive potential than Reid. But, it obvious why old school scouts like Reid more in spite of the production. I'm guessing Reids analytics are better too. He plays aggressively which gets him in trouble without the puck and his skating is good, but not elite.
