Of course I had to put this together after yesterday’s post.
Saves account for the only perfect 80/20 distribution, but in general, historical pitching counting-stat data
breaks down into quintiles conform to Pareto’s ideas fairly neatly.*
Again, it’s all about longevity. The players who were good enough and healthy enough to stick around and pitch the most innings to accumulate all the “good” stats (W, SO, etc.) will also be accumulating the most “bad” stats, giving up the most hits and home runs as well.
