Pens vs Refs - Part 3 - PIM vs Opponent PIM

Today we'll take a look at how the refs treated the Pens versus how they treated their opponents. The chart is quite simple - it shows the ref, the average PIM called on the Pens, the average PIM called on their opponents in those games and the percentage change from the opponent's PIM to the Pens PIM. It's sorted by the number of times each guy saw the Pens - Dave Jackson did 8 games, while Steve Kozari did just one. The results are enlightening - here are a few highlights:

• Of the guys that saw the Pens 6 times or more (there are 7 of them), only one was associated with games that had more PIM against the opposition, on average.
• The biggest apparent bias (in guys who saw the team 4 times or more) was held by Dan O'Rourke, who was in games where the Pens received 60% more penalty minutes than the opposition.
• On the flip side, Rob Schick seemingly loved the Pens, calling only 70% of the PIM on them that he called on the opposition.
• 25 of 37 refs had a higher average for the Pens than they did for the other team.
• Eliminating fighting penalties here wouldn't do too much, as there is usually 5 minutes assessed to each team.

Take a look at the chart - it's pretty intersting.
