GM's comment all the time on how hard it is to make a "Hockey" trade. Both Adams and Guerin are finding out that there just aren't young players of equal value readily available in trade. Most teams want to keep their young, productive, cost controlled players. Here on HFB, we love draft picks and unproven prospects, but GM's(especially ones under pressure like Guerin and Adams) look at things differently. They need good, productive, young players that can start next season in exchange for the similar players that they are sending out.
The one thing that BUF can do, ultimately, is wait JJP out. He is a RFA, and ultimately, the player has to sign, sit, or sign an OS. Sitting is stupid, and Sabres will likely match any OS unless it is crazy money. Not many teams are in a position to do that.
JJP and his agent can squawk all they want, but if BUF can't get what they want in trade then they should just keep him. What's he gonna do, play poorly and sink his value?
