It's an interesting question, Neil was certainly a fan favourite and about as impactful a player as you ask for out of a 3rd/4th liner. I don't however think at any point in his career, a team would have offered up 10th OA for him on draft day.
10th OA is a funny part of the draft. You can land a guy like Rantanen, or you can end up with a guy like Koekkoek. There are more guys like Hodgson Ritchie, and Nichushkin than there are guys like Rantanen taken at 10th, and it's not really close, so yeah, Neil would probably be a great outcome in that narrow view. Strangely 10th OA seems to have done worse historically than 11-15.
Did we target another Tkachuk out of Boucher, I think that would be unlikely, I suspect their projection was significantly more conservative. But one would hope they also were aiming higher than Neil, no disrespect to Neiler, at that range in the draft there are typically a few star players available,
