It's pretty safe to say they are not trading any goalie this season.
Agreed, I think a lot of speculation from outside of the organization is just looking at the Bruins needs and assets at a high level. Do the Bruins need a high-caliber #1 center, yes. Are the Bruins in a really good position at goalie so that they have the luxury to potentially move a goaltender, sure.
Thing is, the the Bruins come up a lot when Lindholm is mentioned, but Coyle and Zacha are producing more if not a similar level to Lindholm. Is it worth moving high-caliber prospects and picks for Lindholm? In my opinion no since I don't think he moves the needle any more than Coyle and Zacha can.
A big reason for the Bruins' success these past two seasons is because they have two #1G in Ullmark and Swayman. Could they move one, sure, but the return isn't going to win the Bruins any more games than having two #1Gs would.
