I think our D of the future will be
Broberg Bouchard
Jones Bear
Samorukov Barrie I think Edmonton extends him
Lagesson
Broberg/Bear - I like Bear's 2-way ability to compliment Broberg. Bear is a smart player. He had some tough minutes last season, and did exceptionally well as a rookie. The more experience he gets, the better he'll be in his own end + more comfortable he'll be making plays offensively.
Samorukov/Bouchard - This just makes... so much sense to me. For me, Samorukov's ceiling is as the #3 guy. He's a rock defensively, has a pretty complete skillset, and has quite a lot of experience playing with an offensive defenseman (& defensive liability) in Merkley. Bouchard may not be a liability defensively at this point in his development, but he's not the guy I throw on the top pairing getting those tough minutes.
Jones/Vet RD - Jones could just as easily be a 2LD in my head in 3 years time, but should Samorukov continue to impress, Dmitri makes a better partner for Bouchard imo.
Lagesson - Unclear what his ceiling is. He was effective at even strength for the Condors (didn't get PP time as far as I know), and is playing well in Sweden.
It's unlikely all these young D stick with the org and all hit their ceilings lol, but one can dream.
