I am lizard king
Colorado had a 77 PPO disparity between Philadelphia in both team's home games.
65 disparity on the road.
Overall? 7 of the top 10 PPO teams were playoff teams. And 11 of the top 15.
I'd highly dispute that actually.
A more interesting point would be to look into the trend of Carolina leading the league (or close to) in opportunities per year. This year was the only time they were not top 3 in the league since 01-02.
IDK why Carolina has been near the top although they have not been to the playoffs much lately.
I'm not sure when the effect I was talking about disappeared, but it was prevalent into the 90s at least.
