Krueger noted prior to the team's game at Madison Square Garden earlier this month how a combination of added size and improved technique has put Dahlin in a position to win more of his 1-on-1 battles as this season has progressed.
Dahlin has learned how to approach different players defensively. He's playing smarter and thinking less, leading to a confidence on defense that has translated to his offensive game. Since his hot streak began on Jan. 4, the Sabres have a 68.4-percent share of goals scored with Dahlin on the ice at 5-on-5.
Sabres assistant coach Steve Smith, who works with the team's defensemen, explained how Dahlin's technique has improved in his own end.
"It's identifying stick positioning, it's identifying body positioning, it's identifying the strength of the other players that he's playing against," Smith explained. "Big, strong guys you can pursue a lot quicker and be a lot heavier on. Some of the lighter players you have to be a little bit more nimble as you skate into the corners.
"I think that's one of the things he's doing, is learning the league, which guys you can slam around a little bit and which guys you need to stay away from. The other side of it is some of those bigger, stronger guys, you just learn how to take away their hands versus trying to contain a guy who's 220 pounds. It's not going to be an easy task for a younger player."
It helps that Dahlin is, by all accounts, a willing student. Smith says the first time he met Dahlin last season, he wanted to hug his parents for the way the defenseman was raised.
"It's amazing how you tell him from one game to the next that he needs to do something a little more often, he tries it almost within the first shift," Smith said. "So, he really is coachable."
His learning has extended to the offensive end, too. Dahlin is capable of what Krueger refers to as moments of "genius" with the puck; he has been since before he even took the ice in a Sabres sweater. He has a forward's ability to handle the puck and a poise that allows him to make plays under pressure.
What Krueger and Smith have noticed this season is an ability by Dahlin to pick the right spots to put that genius on display.
"He's now being patient and waiting until those opportunities and those openings are actually there," Krueger said. "So, it's simple play, simple play - boom, genius. Simple play, simple play, simple play, genius. There's a different rhythm all the time and he's finding that rhythm now, which the great defensemen do, is that mix between simplicity when the team needs it and brilliance when we need it because he can really make a play when he has that space and time."
Smith added: "When you get away with a play standing still on the blue line, you go around somebody, it looks wonderful to the crowd but in a 2-1 hockey game and you're up by a goal, you don't want him trying that stuff because it is a dangerous play.
"So, he's eventually getting to the point where he knows when to take the odds, when to play with the odds, when to go against the odds. At this point, more often than not I find him to be playing with the odds than against them. Last year, it was certainly the opposite, especially early in the season."
