Selected by Washington in the first round (No. 27) of the 2008 NHL Draft, Carlson has 333 points (77 goals, 256 assists) in nine seasons with the Capitals.
Although Carlson was born in Natick, Massachusetts, and grew up in Colonia, New Jersey, he has said he considers the Washington area his home. He lives there during the offseason and plans to have his day with the Stanley Cup there this summer.
"I've lived here every summer since I've been here," Carlson said June 13. "This is my home base and, obviously, the guys that I've been around, the experiences we've had, I love the area and this is all I know."
But Carlson acknowledged at the time that more would go into his decision than his desire to stay with the Capitals. If he had reached the UFA market, he would have been one of the most coveted players.
The free agent interview period began Sunday, and Carlson's agent, Rick Curran, said late in the morning that he had started fielding phone calls from other teams while continuing to negotiate with the Capitals.
Carlson's new contract more than doubles the $3.96 million AAV on his expiring six-year, $23.8 million contract, which he signed in 2012. To create NHL salary cap space to re-sign Carlson, Washington traded goaltender Philipp Grubauer and defenseman Brooks Orpik to the Colorado Avalanche on Friday for the No. 47 pick in the 2018 NHL Draft.
Orpik, 37, has one season remaining on his five-year contract with a $5.5 million salary cap charge. According to multiple reports, the Avalanche placed Orpik on unconditional waivers Saturday for the purpose of buying out the remainder of his contract.
Grubauer, 26, could have become a restricted free agent July 1 but signed a three-year contract with the Avalanche on Saturday.
"Both [Orpik] and [Grubauer] are really good people, well-liked by their teammates," MacLellan said Friday. "You don't like trading away good people, but it's what we had to do to move forward with the team."
