It would certainly make sense for the Buffalo Sabres to look to try to trade Ukko-Pekka Luukkonen out of their three goalies.
Since Ukko-Pekka Luukkonen made his season debut a few weeks ago, the Buffalo Sabres have tried to do a three-goalie rotation. There seemingly hasn't been much rhyme or reason to how they set the rotation other than they go with the hot hand until they struggle and then they make a switch.
