I appreciate that the $$ will be tight, but:
Gardiner is not getting resigned; the LHD will be Reilly / Muzzin / Dermott or Rosen
Trading both Brown/Hyman is a terrible idea. they both do all the corner and dirty work that allows the other players on their line to be successful. and both are signed to relatively cheap $
Puljujarvi may be struggling, but EDM is not flipping him out with a cap dump for Zaitsev, and for the TML russell is a downgrade to Zaitsev
also we don't need Puljujarvi - RW is kinda stocked right now (MM16 / WN29 /KK24 / CB28 / Bracco / Engvall / Korshkov)
I will say the $$ and term given to RFA's do make sense, but may be tough to get MM16 to take a 2 year bridge (hope he does!!)

trades seem way off to me. and resigning gardiner and only paying marner in the 8mil range would be a garbage move imo.
