Well, not really for a 1st round pick 3+ years into his development. Maybe if he was a 2nd or 3rd rounder, but not for a 1st
68 points in 50 games on a bad Plymouth team as a rookie in OHL after his draft are pretty damn good numbers on that team. And then 5 points in 10 games in AHL at end of season...
and then last season as a real young player in the AHL getting 31 points in 54 games is impressive. Most players at 19 are unable to play in AHL and have to be sent back to junior. But he was able to due to being drafted out of USHL.
IMO his development numbers are impressive so far.
I realize when you compare him to some others from his draft that played in NHL last year(Reinhart, Drai, Fabbri, Pastrnak, Ehlers, etc) it looks like he hasn't done as well, but when you compare him to the many others that had to play junior/NCAA/etc once again and hasn't played any pro(Dal Colle, Perlini, Tuch, Schmalz, Scherbak, etc etc etc), his development looks extremely good IMO. That pro experience he had last year was huge for his development
