But points per 60 means you count guys with 4 games played. That doesn't make sense either. Where does his points per game rank over the last 3 years, if the games played is set to 21? The sample size you chose (3 years) only makes sense if you look at guys who played all 3 years.
In terms of actual points, he has 13 points in his last 27 playoff games (the last 3 years), that again, is 39 points per 82, which is his career average both in the regular season and in the playoffs.
The point I'm trying to make is that folks expect too much and then act like he's a disappointment. His production in the playoffs is the exact same as his regular season average. There isn't this big drop off from regular season Coyle to playoff Coyle. The production is the same, the only difference is that he's much more physical.
