I know you're being funny, but to follow up on my actual point: this isn't correct. No one understood "progression to the mean." It was invented because of misunderstanding regression, and has had to be repeatedly explained for it to take hold as a fantasy football concept.
The correct view is to see the mean as the normal state, and the outlier as being movement away from it. Calling it "returning to the mean" would have the same meaning as "regression," and perhaps more clearly explain why regression is a valid word. It is regression (backward movement) in the sense of going back toward the mean, which is the default state.
Progression would imply something changing over time, whereas the presumption here is that there is a mean, and that each "season" is a random variation off of that mean, and not a trend "progressing" in any particular direction,
