If Dubois is indeed traded here, his salary won't be 9M because he'll have forced his way and will have to make concessions. Kent is not trading significant assets, nor is he signing him to 9+. If PLD really wants to come here, it'll show.
I don't think his salary would necessarily come in below Suzuki's as it's a different situation (buying 7 UFA years), but I'd go as high as 8.25M.
Max trade offer:
Dvorak
Harris
FLA's 1st or Kidney/Mesar/Farrell
Max contract offer:
8 years × 8.25M
Your move, Pierre-Luc!
