Going on the assumption that Tatar, Frolik, Staal, Merrill, Gus don't get signed, Drouin is traded and Allen is picked up in the expansion draft, we're sitting on roughly $13.5M in cap. Signing Danault at $5M, Armia, KK, Lehkonen at $3M, Perry $900k (all rough est.) leaved us with about $8.5M in cap. Need a back up goalie but still leaves quite a bit of cap to go big game hunting for an impact UFA of player of need not to mention we can send more cap back in the trade along with other assets that we have against our cap. Also, given our low draft pick in the 1st round and multiple picks this draft with little scouting, we have a ton of assets to trade as well.
Moral of the story, we have plenty of space to bring in a player to address an area of need and after this run, I expect Montreal to be a more desirable location that players may be more open to come to. Hope for a successful off season after a Cinderella run so far.
