You know a ton of 240pound 18 year olds?
The average NHL player comes in just shy of 200pounds
He’s 18 years old, does weight make you older?
Why do you think big players like him historically take longer? It’s not an advantage until you get strong enough to skate with that weight, which take more core strength and that comes with age, not with just more trips to the gym.
Offhand how many top picks you keep comparing him to have that much weight?
Ovechkin was listed at 6’3” and 233 at the draft but he didn’t hit the NHL until his age 20 season. (Because of the lockout, I know, but that’s when he got here.)
Thornton, that ancient 1997 example you reject, was listed at 6’4” and 230. And he was an infamous slow starter.
Slafkovsky is a rawer prospect, and I’m not sure what kind of player he will develop into, but if you look at the heavier players they all first click in the NHL later. Even with the top guys it’s around their age 20 season.
I personally thought Slafkovsky had very little (to none, really) chance of being NHL ready this season, not at 18 at his size.
There aren’t a ton a precedents in general, few skilled forwards come this big, but the precedents of them flourishing in NHL at 18 is non-existent. (Edit: well, I guess Lindros, but that’s Lindros and he held out in his age 18 season.)
I’m not going to play internet debate club here, if you don’t agree with this point then fine. Keep hammering at the kid, I don’t care.
