It's easy to overestimate the value of "a 1st" if you've been picking in the range where they're actually worth a good roster player. No chance LV would deal either Brodin or Dumba for anything other than a top 5 pick, and maybe not then. They'll have to try to be a little competitive to start with for one, and the youth of the players above is such that they should still be a cornerstone on the D by the time LV should be expected to hit bubble team status.
People are underestimating the Stevens effect. Brodin has been far more active offensively this year. He's got a weirdly accurate shot from far out.
