Thornton & Kelly won't be back, and I suspect they're going to go hard after Alex Edler to sure up their D, they'll need to deal some others to clear cap space.
There's no way they'll find place for Edler without gutting their team. If they sign Iginla, there's no space for Edler.
Thornton is probably gone, Kelly has two years left on his deal at a very manageable $3M. Although if they did want to get rid of him, there will be some teams interested. Very solid third line player.
I would not be surprised however if they decided to trade Marchand. Did diddly ****-all for the entirety of the playoffs and I have a feeling they're tired of his shit.
Looking at Boston's cap next year, they currently have $63M committed on 19 players (18 if you discount Savard) and the extras from Iginla's contract.
Smith & Krug looking for raises from their entry level deals, let's assume $3.5M each. So if theoretically Boston decided to trade Kelly & Marchand without taking any salary in return, the money saved is spent on Smith & Krug's raises.
If Iginla signs another one year ~$6M deal, they'll have $69M spent on 19 players. They'll more than likely have to get some of their players from Providence to play on the third line or sign some super cheap UFAs. Not to mention find a goalie at league minimum to backup Rask.
Another way to save money would be to trade Adam McQuaid to save on his $1.6M, but you're not going to be saving much.
