The statistical difference in drawing penalties per team is not even that significant. If you eliminate the two out liars, Nashville who draws on average 11 PIM a game, and Pittsburgh who draw on average 6.8 PIM a game, the difference between the top penalty drawers and bottom penalty drawers is about 1 minor penalty a game.
Most teams don't even convert at a 25% rate on their PP, so we'll take the Oilers as the average at 20% conversion.
If the Oilers do indeed have a conspiracy against them, by not getting an average 1 more PP a night are getting screwed out of a goal once every 5 games. For a total of 16 goals a season!
