I like the same old speculated guys: Matthias and Bozak. Ott and Goc would fit nicely as well.
I really like Stastny, he would bring a lot of quality to our 3rd line, and he could also play with Kesler on the 2nd. The thing is his cap hit of 6.600M, we're already in a lot of trouble to meet next year's cap, he wouldn't help at that matter as he has one more year in his contract.
Is there a team in the NHL would be willing to trade for a player with a huge contract to try to win the Cup and when it's over use one of their "free" buyout? Beeing a GM if I had a chance to rent an interesting player like that, I would do it.
