I believe the consensus on this board is the Pens will not win the Cup this year and that it may not even win the East.
Since the Pens have limited cap space and really limited assets to trade unless they want to throw away the future as Shero did, all of JRs this year, if any,moves should be for 2015 and beyond. Just bite the bullet.
First, Martin should be traded but since he is a UFA he will only bring back picks and or a prospects, hopefully a F from a contender. Since he is a UFA, the bottom feeding teams have no interest in him.
Second, Erhoff probably has priced himself out of PGH. He will get a bigger payday than Nisky and Orpik. If the pens sign him, it should be for no more than 3 yrs at 5.5MM per yr. But some GM will give him at least 4 yrs at a 6MM minimum.
As some one suggested, Letang, Maata and Erhoff are your first 3 D with Despres, Dumo, Borts and Harry rotated as your bottom 3 D. Scuds simply should not play. He is just plain bad and should be bought out next year. He is untradeable. No bottom feeding team wants him and any contending doesn't want him. Sit him and MJ please don't play him in the playoffs. Just look at what he did last year in the playoffs.
IMO, The only Pen's prospect that should be traded is Pouliett. If he brings a good F prospect (like an Etem), trade him. He will never be as good as Letang. He is weaker defensively and offensively not as gifted as Letang.
