Considering the recent success of the Pens' PK, I started wondering: are the Penguins better defensively when they are shorthanded than when they are at even strength? I'm no math whiz, but I considered some of the team stats at even strength and on the PK and simplified the season so far into two minute periods (the theoretical equivalent of a PK or PP). I would love to get a more accurate calculation later. Here's my work:
I broke down all of the minutes (not counting OT) the Pens have played so far: 1500 minutes. I then assumed that all penalty kills and all power plays last exactly two minutes, and subtracted all time on special teams from that total, leaving me with 1072 minutes. I divided by two to find the number of two minute even strength periods, or 538. The Pens have given up 49 even strength goals. This means that the Penguins give up an even strength goal about 11% of all even strength two minutes periods. The PK gives up a goal every 10.2% of two minute short handed periods.
According to these numbers, the Pens' PK gives up fewer goals than the team does at even strength on a per-two-minute basis. Of course, it's simplified, but it's still remarkable.
