I would bet not conditional. Buffalo is gearing up for a long playoff run and to trade one of their few tradeable assets for a pick conditional after the year makes no sense. They have to be clearing salary and using the Nashville pick for a bigger move later.
To me, this trade is worse for Buffalo if nothing else goes down.
by giving up the 1st rounder, they can now talk to him about a long term contract without any other teams playing a part
So everyone lets make him feel welcome so he wants to stay here and not rip him for every rebound he gives up and soft goal he lets in (a la Nitty and Esche) or run him out of town (Calder and hopefully York)!!!
