He was given ES for all the wrong reasons IMO - potential and citizenship. He showed flashes at 14/15 of having an exceptional skillset, but I can't justify giving a kid the status if they can't bring it each and every night and absolutely dominate their peers. I remember at the time I questioned the decision as it was the 3rd in 3 years as well after Ekblad and McDavid, but there were lots of people like Brian Killrea and other OHL scouts who said he had a higher ceiling than any 14 year old they had seen, so I myself (after seeing a few flashes) could understand the hype.
I really hope he figures it out, I know the ability is in there but I haven't followed him closely enough to see his progress.
Edit - I will also say it maybe should have been a red flag when he got passed over by 3 teams in the OHL. Every other ES player has gone 1st overall, and I remember John McFarland was rejected on the basis that he would likely not have been the 1st overall pick. It should almost be a guarantee that an ES player is going 1st, looking back it was a puzzling decision.
