More often than not, the team that gives up the best player loses the deal in the long run. I can't see Ottawa getting a player as good as Spezza back.
To the original post, I would not trade Spezza for prospects and a pick. I doubt that I would trade him anyways. If I were to, I would want a young established star and a first round pick or two. Vermette, Fisher, Kelly, and McAmmond down the middle isn't horrible if you add in 1 or 2 better wingers and an offensive d-man.
Fisher/Kelly - same sort of strong defensive player who chips in a point every other game. Combined, they are a cap hit of 6.4 million for the next four years including this one. Does this seem like a luxury to anyone else?
My bet is that 2 of Kelly, Vermette, Neil, and Fisher are gone by this time next week. It just isn't working anymore.
