"The stats shown here are how each player performed on average in completed $80,000,000 Auto Leagues he's appeared in."
Yeah Ballpark is huge and I know it's a tool that none of lean too heavily on considering the objective nature of what the cards can do. Frankly I'd read into usage more than average numbers because of my above comment. Kinda disagree about sample size not being a critical difference in numbers. It'd explain why certain guys we may like have more muted numbers. I suspect many players are a small # of seasons.
For ballpark, the could always show the average BP rating like:
9.6- 8.8 - 11.4 - 8.4 That'd be asking alot.
Unless SOM is opposed to it, the usage numbers would be so interesting.

This is what DiamondDope actuals used to do and that usage data was amazing.
