Come on...we know you have a little bias toward EDM but Bouchard definitely has more upside than Barrie and probably is already better than he was...
I think a realistic comp for him could be John Carlson.
Carlson was voted 2nd, 4th, and 5th for the Norris... that is a pretty high goal for Bouchard when there are a bunch of better D around his age.
Carlson was amongst the best for a few years.
-- edit --
Just to put this into perspective, here are some U25 D (not including prospects)
Dahlin, Fox, Makar, Heiskanen, Hughes, Sergachev, Seider, Miller, Dobson, Power, Chychrun, Sanderson, and Byram.
He's better than some but worse than a lot of them too.
Now if you include prospects it gets even harder for him to be a top D.
Nemec, Hughes, Edvinsson, Jiricek, Clarke, Nikishin, Hutson, Faber, Reinbacher, Willander, etc...
