1. More of the same: The Rangers were at their best this series in Game 6 in terms of sustaining a forecheck, being the more aggressive, faster-skating team and not giving up any power plays. It’s going to be hard to maintain that level of energy tonight, not only on the second night of back-to-back games but on the Capitals’ home ice, where the Rangers have lost all three games in the series. 2. First soft goal loses: The Rangers’ Henrik Lundqvist and the Capitals’ Braden Holtby were outstanding in Game 6. Neither team can afford even the slightest slip-up from their goalie in Game 7. 3. Desperately seeking their power play: The Rangers went 0-for-5 on the power play with seven shots in Game 6 and are a woeful 2-for-26 in the series. They are 0-for-11 on the man advantage in their three previous games at the Verizon Center and that likely cost them a chance to win Games 2 and 5. Plus, the Rangers are 0-for-3 on 5-on-3 power plays. If that trend continues tonight, the Rangers will be hard-pressed to win a road game.
