Carlson, who is never one to talk about individual accolades, deflected the question when asked about the Norris Trophy.
"I think it should reward the best defenseman," he said. "It's plain and simple. Whatever that is, whatever category you want to put people in or talk about a certain player a certain way, who would you want on your team the most? That would be the award, for me."
Capitals coach Todd Reirden has seen Carlson blossom since the former joined Washington as an assistant for the 2014-15 season.
"Obviously John is having a terrific year and continues to get better and better every season," Reirden said Tuesday after Carlson was selected to play in the 2020 Honda NHL All-Star Game. "It's been fun to watch for the last six years. Credit to him having a good plan in place in things to continue to work and grow into, so that's been outstanding."
Carlson could become the first Capitals player to win the Norris since Rod Langway in back-to-back seasons from 1982-84. Though Carlson has developed chemistry with many of his teammates in his 11 NHL seasons, perhaps no one knows him better than his dad, Dick Carlson.
"Great start, he's playing well and the team is playing a little more aggressively in certain parts of the game, which has kind of led to a few more points here and there," Dick Carlson told the Capitals website Dec. 16. "I've gone back watching him forever, so I don't know if he's playing that much different. I've always known he's had this kind of stuff in him, but a lot of things need to go right for you to have success so far as far as points goes.
"He hasn't and neither have I put too much on the points total. It's just play the game the right way and let it all happen. This year it's working out pretty good."
