There are a lot of rumours surrounding the Boston Bruins, they have stated that they want to get faster and bring in secondary scoring this off-season and they are going to be aggressive in free agency.
With the rumours of Jake DeBrusk potentially leaving the Boston bruins that could open up a spot for Ehlers, the Bruins would be losing a good young winger but if they could manage to acquire Ehlers it might even be looked at as an upgrade.
