LA has 20 mill to finish out their roster which includes 5 forwards, 2 d and 2 goalies, so that's unlikely.
Carolina needs 5 forwards, 3 d, so very possible, but Carolina has some real good RFAs and UFAs.
Dallas needs 2 forwards, 3d and 1 goalie.
Islanders don't really have much in terms of assets. They need a handful of players and only have 5 mill.
Capitals don't have much unless they're trading Leonard. Caps are over the cap for next season, but that might not include Backstrom and Oshie may LTIRetire
Blues have the assets and cap space to go for it.
