Jack Hughes is an unbelievable skater. Top tier.
Yeah, even if Lafreniere is a good or above average skater, Hughes will be top 10 in the league when he enters. It'd be similar to me saying the big difference between Matthews and McDavid, is Matthews size. Matthews is a good skater, especially for a guy who is around 6'2 220, but McDavid would torch him in open ice.
Lafreniere looks like one of the most complete wingers in ages. He ticks all the boxes. Good size, great hands, very-high IQ, above average to good skating, plays hard, and plays physical.
The one trait I really like about Lafreniere appeared in his highlight reel goal, and it wasn't the part on the highlights. Prior to that breakout, he had a failed entry with a sloppy turnover. Instead of waiting for his team to get the puck back and get it to him (not an uncommon thing for star wingers in junior hockey), he was skating his ass-off to win the puck back, which he did by stripping a Swede and then driving up ice. It reminded me a bit of the differences between 17 year old Mitch Marner and 17-year old William Nylander. Nylander would wait for his teammates to get it back for him, and then attack again. Marner was like a dog on a bone to get that thing back. Here's a quote about it from an NHL scout in the 2015 Black Book about Marner.
“You don’t see a player with his talent backcheck like that everyday.”
I'd still lean Hughes on this postion. He has a bit more gamebreaking skill and has the chance of playing the more important question. But, Lafreniere is the best Canadian winger since at least Hall at the junior level. Past that your debating guys like R. Nash and Dany Heatley.
