I would consider including prospects like Dylan Strome, Kirill Kaprizov, Thatcher Demko, or Jon Gillies in the right package for a high first round pick or player that tickled my fancy.
I might even consider trading Crosby, Kessel, or Stamkos for the right package of players, prospects and/or picks. I doubt it, but it's not impossible if there were a couple of young elite studs and a high first round pick in the works.
