The reason for the move is the Sabres are not making any big signings this year. They want to leave room for their prospects to keep developing. They might add a goalie but that's about it. They have two players coming to from Rochester, Quinn and Peterka, and they want to save slots for them.
 
	 
 
	As for what future considerations are, the Sabres got the 7th and Dallas gets nothing really.
