Wright did get hurt (as many OHL kids did) by not being to play competitive hockey for well over a year. Long term could cause some issues, essentially missing an entire year of development (even players who miss time with serious injuries are still able to practice somewhat and do other activities)
I believe he had the option to play overseas or even in the USHL. A bunch of other top prospects took advantage of this - Bedard played a handful of games in Sweden, Brandt Clarke played 26 pro games in Slovakia, and Matt Savoie played 34 games in the USHL.
For whatever reason, Wright just decided not to. I think that was a mistake on his part.
He really didn't seem all that motivated in the 2-3 seasons after his stand out 15-16 year old season. His on ice effort in his draft year was abysmal.
But since the start of last season, I've seen a notable improvement in his on ice engagement and two way play. He's never going to be an elite offensive player but I think he could become a ~25-30 goal 50-60 point scoring forward who isn't a defensive liability.
