Unlike last offseason, when the Capitals kept most of their roster hoping it would give them the best chance to repeat, there will be changes. There are decisions to be made on potential unrestricted free agents such as forwards Brett Connolly, Carl Hagelin and Devante Smith-Pelly, and defenseman Brooks Orpik.
That the core, led by Ovechkin, Backstrom, forward T.J. Oshie, defenseman John Carlson and goalie Braden Holtby, will remain intact for at least one more season is comforting, and reason to believe they can win the Stanley Cup next season.
"We have the ability in our room to do that, especially with our core group," coach Todd Reirden said. "I don't see any reason why we would expect anything less than coming back and contending for another Stanley Cup."
But how far the Capitals Cup window extends beyond next season will also be impacted by how they handle this offseason, beginning with Backstrom and Holtby.
Each will be eligible to become an unrestricted free agent after next season if they aren't signed to new contracts before then. The Capitals are permitted to do that beginning July 1.
MacLellan said he will make initial inquiries on what it will take to re-sign each but was vague on how aggressive he will be.
"They both have a year left, so we'll talk to both of them," MacLellan said. "We'll have decisions to make as we go throughout the year."
Regardless, it seems almost certain Backstrom, who turns 32 on Nov. 23, will get a new contract at some point. MacLellan considers him an essential part of the team's leadership group, as Ovechkin's longtime center and right-hand man
What will happen with Holtby is less clear.
Holtby turns 30 on Sept. 16, and by the 2020-21 season, Washington's goalie of the future, Ilya Samsonov, the No. 22 pick in the 2015 NHL Draft who played for Hershey in the American Hockey League this season, should be ready to play regularly in the NHL.
