There were a lot of rumours about Ullmark being traded at the deadline, but his NTC caused the Bruins to not be able to complete a deal. It seems the Bruins are still trying to explore some of those options this off-season.
With this report it looks like the Boston Bruins are looking for a hefty return package to trade Linus Ullmark, but you aren't getting an average goaltender, you are getting a really good starting goaltender who won the Vezina Trophy last year.
