All six teams have something to prove in Friday's Stanley Cup playoff action

Montreal Canadiens

Prove: They can do it for 60 minutes.

Montreal may have snuck into the playoffs, but its performance hasn't looked out of place against Washington. The Habs have charged hard in the third period of every game, outshooting Washington 28-12 in all situations in the final frames. In that time, they've also won the high-quality battle with eight all-situations high-danger chances to Washington's one, according to Natural Stat Trick. The Capitals have outscored Montreal 4-1 combined in periods one and two of this series, allowing them to play more defensive-oriented later in games. If the Canadiens want to take advantage of last change at home, playing constantly from behind isn't the answer.

Carolina Hurricanes

Prove: Convert on the power play.

The Canes are just 1-for-6 on the power play, worth noting with how potent some of their potential future opponents have looked with the man advantage this postseason. Carolina has created opportunities in their six attempts, but they are 14th in power play shooting percentage among the 16 teams in the field. Up 2-0 on the Devils, it may not matter in this series, but it will later.

New Jersey Devils

Prove: They are more than Jack Hughes.

The Devils are playing at a disadvantage without one of the most unique players on the planet. Nothing they can do about that — something else has to give. It's not encouraging that the Devils are currently scoreless on the power play. It's even less encouraging that, down in the series already and trailing going into the third period, the Devils only mustered a single high danger chance in 15:15 of 5-on-5 play in the third period of game two. 

Los Angeles Kings

Prove: They can do it away from home.

The Kings were the best home team in the NHL this season. Quantifying what that means is tough — a likely combination of difficult opponent travel, coaches taking advantage of the home-ice last change and player comfort level. As good as the Kings have been at home and as good as they have been in this series, they went 17-19-5 on the road this season. They did finish strong on the road: 5-2-0, including a 5-0 win in Edmonton at the back-end of the regular season. 

Edmonton Oilers

Prove: They know the puck isn't a live grenade.

A goalie change will only do so much for the Oilers, who are down 2-0 in a series where they look nothing like the team that found multiple ways to win games on their path to the Stanley Cup Final last season. While the overall defensive metrics haven't been bad, the chances they are allowing to Los Angeles have been loud thanks to bad puck handling, disappointing compete level and a struggling penalty kill.

They've been outscored 7-2 in the first two periods of the first two games. Without top-four defender Mattias Ekholm, they're at a disadvantage. It's an even bigger disadvantage when they're being outworked.
