Your obvious weakness is at centre. Luckily for you, centre is the most deep position in fantasy hockey right now. Trading kipper is something you might want to explore, but i think you can do better than this trade. Don't forget that Huet is riding the bench right now. And Spezza is somewhat overated this year. Try moving Kipper in return for a Toskala, Bryzgalov, Backstrom, someone who will still give you decent goaltending in return.
DO NOT trade Markov.. He plays the pp on one of the best teams in the NHL and is on the brink of breaking into that top tier of D-men alongside Lidstrom and Phaneuf
