Is it that simple though? Yes, the state of our defense undoubtedly prohibits us from competing next year (and probably for another 2). However, it looks somewhat promising once we move past that and fits the timeline quite well in that sense.
ADA, Fox, Hajek, Lindgren, Rykov are all on the cusp of being NHL ready (surely not all will pan out, but that's 5 right on the doorstep). Miller, Lundkvist, Keane, etc...are a few years off, but represent strong prospects.
Buch and whoever we draft at 20 would strengthen that squad down the line, whereas Trouba, who has quite a sketchy injury history, is not necessarily a sure thing.
It's an interesting proposal, but I'd probably pass and see what opportunities arise in 2 years if one of our guys doesn't emerge as a top pairing guy.
