So when the clock struck noon on July 1, it didn't take long for the Bruins to ink Moore to a five-year deal worth an average annual value of $2.75 million, a move that deepens Boston's defense corps and provides versatility for coach Bruce Cassidy.
"The last two years in the playoffs, really, when you're running through 10 [defensemen] two years ago - we went through all eight this this year. Brandon [Carlo] hasn't even had a chance to play in the playoffs," Sweeney said of the importance of adding bodies on the back end, while also not ruling out a trade involving one of his existing defensemen.
"It may seem congested as we sit today, but to tell you the truth, we're really happy, because when you get into the year and you're wondering, 'OK, where does that guy come from?' You've got to go find him and acquire him and [who knows] what that acquisition cost may be."
In addition to strengthening the team's defensive depth, Sweeney was also interested in adding size, particularly on the left side. With Torey Krug and Matt Grzelcyk both standing at 5-foot-9, Moore and his 6-foot-2-inch frame brings some beef and brawn behind Zdeno Chara.
With that size, however, also comes mobility and some timely scoring touch. The eight-year NHL veteran - who has also played the right side - posted seven goals and 11 assists in 81 games for the Devils last season, after notching a career-high 12 goals in 2016-17. Since the NHL shifted to the 3-on-3 overtime format in 2015-16, Moore leads all defensemen with six goals in extra time.
"We felt that the opportunity to add a player of that nature fit into how Bruce wants to play: getting back to retrieve pucks, be able to defend with his feet against faster, bigger, stronger players complements the group we have," said Sweeney. "Overall, I think we have better balance in terms of what we can present each and every night as a matchup for our team."
