I think Florida will be aggressive after moving Matheson. A Krug-Ekblad Yandle-Weegar top 4 would be legit.
Vegas is already heavy on the left side with Theodore, Schmidt, Martinez, Holden, McNabb. I think Martinez at least plays on the right
Colorado has Girard and Graves on the left with Byram on the way. They could also use help on the right.
If we were to sign Krug, we'd have him, DeKeyser, Nemeth, and Staal as a scratch, with Cholowski playing in GR. The right would be Hronek, Seider?, Biega, Lindstrom. It's starting to fill up, but I don't think signing Krug would push someone out who 100% deserves to get minutes.
