Everyone knows that the PK has been a huge weakness of the Caps all season.  And I assume most remember the game against Dallas two weeks ago, which was lost largely due to poor PK, as the Caps went 0/2 and allowed Dallas to get back into the game.  But since then, the PK has been phenomenal.

• Carolina (at home): 4/5
• Tampa Bay (at home): 1/1
• Chicago: 2/3 (The one goal was on a 5-on-3, and the rest of the PP was killed so does that make it actually 3/4?)
• Florida: 4/4
• Carolina: 4/5 (The one goal was on a 5-on-3, and the rest of the PP was killed)
• Tampa: 4/4

Total: 19/22=86%
5-on-4: 19/20=95%

Obviously, there's not a large sample of games here, so it's hard to draw any conclusions.    Corvo (and Belanger?) spoke out after the game, saying how they were used to less passive power plays.  And BB mentioned specifically how the Caps would work on the PK.   But it's very possible that this is simply due to the small sample size and the relatively weak oppositions.

To my eyes, the PK does look more aggressive and has contributed some to the recent success, although I could not say to what degree.  What do other people see as the reasons for this improvement?

And to what degree could this improvement help us in the playoffs?
