Would likely mean trading Doby and/or Faksa somewhere, and SJ would likely retain some salary.
As to why we'd want a 37 year old defenseman...have you met Jim Nill? But in seriousness, he has history with DeBoer and Pavelski, he's a right handed defenseman (which they desperately need), provides physicality and actually still contributes offensively at a decent pace.
If this were to happen though, definitely feels like one of those deals where it looks bad in year 3...if not sooner.
It may work though as his contract would come off the books at the same time as Benn & Suter. That would give the Stars some immediate help but also allow for big moves in a few years. Nill may be thinking that there's a 2-3 window with this group and then the ability to reset with no downtime after the 24/25 season.
And lets face it. Miro made Roman Polack look good, and Burns is light years better than that.
But like most of these leaks, probably won't happen. Apparently Dallas and SJ are "far apart" in negotiations.
