Re-signing Eller, 28, without increasing his $3.5 million average annual value from his expiring contract also might help the Capitals re-sign defenseman John Carlson, a potential unrestricted free agent on July 1. MacLellan said the salary cap is projected to increase from $75 million this season to $79 million next season.
So, with Eller's salary cap charge unchanged, the Capitals should have some additional room in their budget.
"I just think that's a good price for a third-line center," MacLellan said. "So, it helps us on the overall cap, regardless of the number."
MacLellan said he has already had some discussions with Carlson's agent.
"I'm not going to comment on negotiations, but we're going to do everything we can to bring him back, yeah," he said.
Knowing Eller will be back next season also gives the Capitals some stability among their forwards should they choose to trade one to upgrade their defense. Forward Andre Burakovsky's future appeared unclear after the 23-year-old was a healthy scratch for their 4-2 win against the Columbus Blue Jackets on Friday, but coach Barry Trotz said Saturday he expects Burakovsky to play against the Detroit Red Wings on Sunday (3 p.m. ET; SN1, SNE, SNO, SNW, TVAS, NBCSWA, FS-D, NHL.TV).
After Burakovsky signed a two-year, $6 million contract last summer, the Capitals, who selected him with the No. 23 pick in the 2013 NHL Draft, hoped he'd score at least 20 goals this season, and he has 11 points (four goals, seven assists) in 28 games.
