The Rangers have had an unbelievable penalty kill in the playoffs—killing 85.9 percent of their penalties.
So why change anything?
It's all about size.
The Kings are a big team, and they use that size well on the power play, where they have converted 25.4 percent of their chances.
They do it with Kopitar, Jeff Carter and Drew Doughty, all sturdy players.
In order to neutralize this high-powered unit, the Rangers need to pair Boyle with Rick Nash on the first penalty-killing unit.
Hagelin is a fine penalty-killer, but at 5'11", 186 pounds, he's a flyweight compared to the heavyweights from Los Angeles.
Nash, at 6'4" and 213 pounds, is better suited to clash with the Kings. Besides, his defense has really stood out in these playoffs, even though he isn't scoring. As the winger told Larry Brooks of the New York Post:
It’s not about individual numbers when you’re playing for a winning team. It’s about doing whatever you can to help the team. ... Does it matter? Whatever you do, you need to be able to do something else if that’s what the team needs. That’s what I’m trying to do now; whatever the team needs from me.
The Rangers will, once again, need their penalty kill to be successful. Putting Nash's size on the first unit will go a long way.
