Trades are going to be tough with only a half dozen teams really being able to take on salary. Penguins would like to trade Bjugstad, but, nobody is going to acquire him for just picks or prospect. Cheaper to buyout his one remaining year. Would be 600K cap hit this year, and 1.75M cap hit in 21-22 season. Jack Johnson, as much as we'd love to see him bought out, with 3 years remaining, thats a 1.5-1.9M cap hit for 3 years, and another 3 years of around 900K...too expensive. Ease POJ into the lineup, rotating him in and out with JJ.
Murray needs to be moved, because he will cost too much to resign. 3rd pairing RD is a position of need. Jokiharju would be a cheap get, and Buffalo needs a goalie. If they don't want Murray or don't want to move Jokiharju, find another team (there's 5-8 of them) that need a goalie and can give up a young 3rd pairing D-man with upside.
Jarry, McCann, and Simon...I've given cheaper, shorter term deals to deal with the financial issues, but, the 23 man roster below has plenty of room to increase salary to these 3.
Poulin is NHL ready. He was a top 3 player in the Q this year. Start him on 3rd line, and if he excels, he can swap with Simon and move up with Crosby.
