In a division as tight as the Metropolitan, Holtby has been a difference-maker, helping the Caps collect a number of points they might not have otherwise collected.
In making one of those overtime stops against the Blues, Holtby handed praise to Carlson, who learned on his 28th birthday that he would not be representing the Metro Division in Tampa despite a stellar first half.
"I thought Carly did a great job of playing that," says Holtby, "forcing [the shooter] to delay, giving [Evgeny Kuznetsov] time to get back and force them to make a lower percentage shot. That's the one thing you want to do on a two-on-one or a three-on-one; you don't want to give them a breakaway. You want to force them to make a play and buy time for guys to get back and I think Carly did a great job of that. And realistically, he set me up to be able to make that save."
It's not just his work in his own end that makes Carlson worthy of selection to this season's Metro Division All-Star squad.
Carlson ranks second among all NHL defensemen in both assists (29) and points (34) this season, trailing only Dallas' John Klingberg in both categories. In just 43 games this season, Carlson is already only three points shy of the 37 he posted in 72 games in 2016-17. He has recorded a point in 20 of Washington's 27 wins this season, trailing only Ovechkin in that regard. Carlson's averages of .67 assists per game and .79 points per game are both career highs.
Carlson also ranks fourth in the league with an average of 26:17 in ice time per night, a career high figure. He has been Washington's ice time leader at night's end in 34 of the team's 43 games this season.
Each of the eight teams in the Metro must be represented by at least one player, and each division's roster is roughly half the size of a normal NHL roster. All-Star squads contain only 11 players, six forwards, three defensemen and a pair of netminders.
