I voted Boqvist. Bouchard feels like a chychrun type pick. He's closer to his ceiling and much more likely to hit it than Boqvist, but his ceiling, to me at least, seems in the average #2 or good #3 area, and floor being #4 or 5. Boqvist seems like a guy that if you told me in 10 years he was a top D-man in the league I wouldn't be surprised and if you told me he was a bottom pairing guy I wouldn't be surprised. But right now Detroit should be swinging for the fences, because the last couple drafts they've been trying to bunt for a base hit.
That Chychrun comparison won't work, imo. I understand the ceiling thing, but Chychrun was hyped year before the draft to be 2nd overall and then fell to 17th because of mediocre season. Scored 49 points in 62 games for Sarnia, where Konecny was the leading scorer with 101 points.
Bouchard has been biggest risers on draft year, exact opposite of Chychrun, because he has been phenomenally good. He did lead the London in scoring as a defenceman by 30 points (!) before the best forward Dunkley in 57 points. I repeat, Evan Bouchard scored 25 goals + 62 assists = 87 points in 67 games. And this number is the highest age-adjusted + team-scoring adjusted number (my own formula) no defenceman has ever scored in OHL on the last decade. Also better what Drew Doughty did at 2006-07. It's really impressive, best scoring player by far in a pretty low-scoring team. I always give huge value for scoring x amount of points in a team which scores 300 goals for or which scores 200 goals for.
Bouchard was 18.4 year old at regular season and where Chychrun was 18.0 years old on his last OHL season. Also, if you take these age-adjusted things in account, Bouchard's 2016-17 season as 17.4 year-old is equal to Chychrun's season at 18.0 year-old.
But yeah, you preferred Boqvist over Bouchard. I don't mind Boqvist either, but just have a gut feeling, that he is not available when we pick in any scenario. He goes most probably at 4-5 picks, when we either win the lottery and get 1-2-3 picks or if we don't win, we pick at 6-7-8. I think Boqvist goes exactly there at 4-5 where we aren't picking.
