"I think it's a lot easier to make this team worse than it is [to make it] better," he said. "If you make a major change, what's it going to involve? Trading a franchise player, blowing the whole thing up? I don't know that that makes sense."
Some change is inevitable because of the NHL salary cap. Defensemen Kevin Shattenkirk and Karl Alzner, and forwards Justin Williams and Daniel Winnik appear destined to sign elsewhere as unrestricted free agents. MacLellan said he remains hopeful of re-signing right wing T.J. Oshie, another potential UFA who tied with Ovechkin for the Capitals lead with 33 goals this season, but that is far from a certainty.
MacLellan's priority is to re-sign Washington's five restricted free agents: forwards Evgeny Kuznetsov, Andre Burakovsky and Brett Connolly, and defensemen Dmitry Orlov and Nate Schmidt. That and leaving roster room for some prospects to play next season might turn out to be the extent of its offseason moves.
So if the Capitals are going to be a playoff team again next season, they'll need some of their returning players to play better. That starts with Ovechkin, who will turn 32 on Sept. 17 and has begun showing his age.
Ovechkin's 33 goals were his fewest in a full season since he scored 32 in 2010-11, and his 16 even-strength goals were his fewest in a full season in his NHL career. MacLellan acknowledged part of that was due to Trotz cutting Ovechkin's ice time to try to keep him fresh for the playoffs, but said it was "a down year" for him regardless.
MacLellan said Ovechkin needs to make some changes his offseason training to come back next season in better shape, something Ovechkin acknowledged on May 12. He also said Ovechkin needs to adapt his game to the way the NHL has changed.
"He's going to have to think of ways he can evolve into a player that still has a major impact on the game," MacLellan said. "The game's getting faster. He's going to have to train in a different way, a more speed way instead of a power way. He's going to have to make adjustments to stay [relevant] in the game."
MacLellan said he doesn't believe taking the captaincy from Ovechkin is one of the answers to the Capitals' problems, but it sounded like it's an idea he's considered.
"I don't know that that's an avenue we'd want to pursue right now," he said. "I mean, he's our captain. He's been a big part of this franchise over the past number of years and it's nothing we've talked about recently."
