In the end, however, the Bruins felt that waiving Backes - who had dressed for just 16 games this season - was in the interest of the club moving forward, particularly with young wingers Karson Kuhlman and Anton Blidh returning to full health.
"It's something that we had discussed internally with [Bruins GM Don Sweeney]," said coach Bruce Cassidy. "We just felt that there were some guys coming healthy, like we did with [waiving Brett Ritchie on Thursday], in terms of Kuhlman. Blidh is getting closer. Are we going to look at younger guys?
"We just felt that, at the end of the day, you do what's best for the team, what makes you the best team. Ultimately, Donny put him on waivers feeling that that was the best thing. From here, we'll see where it goes for David."
Backes posted 38 points (17 goals, 21 assists) in 74 games during his first season in Boston in 2016-17 and added 33 points (14 goals, 19 assists) in 2017-18 as part of a strong third line with Danton Heinen and Riley Nash. Backes, however, played just 57 games in his second season as illness (diverticulitis) and other injuries limited his playing time.
Those injury troubles - including several concussions - continued over the last two seasons, making it more difficult for Cassidy to find Backes an established spot in the lineup.
"I have a lot of respect for the person as a human being, what he's accomplished in this league," said Cassidy. "We brought him in to give us some of that bite - that's been a subject around here for the last few days…it was there for a while and then some concussions came into play. I think that affects your decision as a coach when you put a human being on the ice.
"We saw that a little bit last year with David, trying to play a little bit into that role and found himself in two or three scraps. I don't know if that's the ideal role for him. But good for him to go out and try to carve a way to get back into the lineup.
"As a coach, I told it to the players, as a guy that you know as a dad, who has two young [kids], you always want to be careful that you're pushing guys to play a certain way. Now you've got a guy who knows he might be one hit away from having some damage.
"You've got to be careful with that. I know it's a business but that is the human side of it…that was a bit of an issue for me to push him in that direction."
