You make it sound like Bonino is the 3C etched in stone throughout the entirety of his contract. Kamenev is pretty good trade bait, I agree but just because Bonino is signed doesn't mean he's destined to be the 3C at best here.
I will trade the possibility that Kamanev could one day become a legit 2C for a legit shot at the Cup before Pekka is any older.
The days of prospect hoarding because we are still building are over. And even if we keep Kamanev, if we can sign Duchene in two years(as many seem to think we could) then that means Kamanev is permanently 3C at best, and then only if he can beat Bonino.
I wouldn't trade Girard, Fabbro, or Carrier, but Kamanev just doesn't seem to have a spot, at least not at C. Might as well spend that coin while it has value, because if he doesn't make the team out of Camp next year he's going to be looking like a bust
