I think the Blues biggest weakness come playoff time is that their d-men get very agitated by a heavy forecheck so ideally, I would like to add a physical, nasty top-4 LD to pair with either Petro or Shatty.
In return, I'd like to not trade anyone from the current roster if at all possible unless a replacement NHLer is also returning in the deal and/or another deal. I'd like to keep any future 1st rd picks and prospects Fabbri, Barbashev and Schmaltz...but of course, everyone is available for the right price.
PS. I know what I want to happen has about a 1% chance of actually happening.
PPS. while upgrading Bergy's spot would be ideal, I think there are more pressing weaknesses. But if Army could somehow swap out Bergy for someone like Ward or Brouwer then sure, why not.
