Sure, but Patrick Kane's first three season's after he was drafted were all in the NHL, and he put up 72, 70, & 88 points. He led Chicago in scoring in his first year in the league as a 18/19 year old.
So if you're making comparisons to some young guys in the league right now, he's quite a bit ahead of a guy like Nylander (who wasn't even in the league until his draft year +3, and then only put up 61 points as #4 scorer on his team). Guys like Eichel, Laine, Matthews, etc if you use a Patrick Kane comparison, should probably get caphits around 8.5M under the current cap, and not ~10M. Though because Eichel signed for 10M, Draisaitl signed for 8.5M, etc, it's going to push Laine/Matthews contracts quite a bit higher than they should be.
