"That's a nice compliment, but I don't approach it that way," said Niskanen, the 31-year-old from Virginia, Minnesota. "I try to play as well as I can within my role. I guess in a way I try to set a good example for younger players. But in the playoffs, you're just trying to do your job as well as you can and be ultra-competitive and play to win."

Niskanen has been a workhorse for the Capitals during the Final, leading all players in average ice time (25:05). He played 27:13 in Game 2 and 27:16 in Game 3. He leads all players in the Stanley Cup Playoffs with 503:30 of even-strength ice time and 55 blocked shots, helping the Capitals become a stingier defensive team the longer the postseason goes. Washington has allowed 11 goals while going 5-1 in its past six games -- six came in a Game 1 loss to the Golden Knights -- and 2.52 goals-against per game in the postseason.
"He's been awesome every game, really, this whole playoffs," said defenseman John Carlson, who leads the playoffs in total ice time (590:10). Niskanen is second with 585:01. "He's been our rock the whole season, too. We always rely upon him in every situation. We're certainly better when he's on the ice."
In his 11 NHL seasons, Niskanen has qualified for the playoffs nine times and played 117 postseason games, but had never reached the Final. He's had chances to win the Cup with the Dallas Stars, Pittsburgh Penguins and, for the past four seasons, the Capitals.
Why are they so close to succeeding this time?
"I don't have a good answer," said Niskanen, who has nine points (one goal, eight assists) in 23 playoff games this season. "I do know that as a group, this is the most committed group that I've been with. I don't think it's the most talented team I've been on. But it's the most committed to the dirty, unheralded type of plays that are so important, that allow your skill to come out. And everyone has bought into that."
Away from the ice, Niskanen, who signed a seven-year contract with the Capitals on July 1, 2014, took the blame for one of the toughest buys in the Final on Monday.
