for instance, kershaw has negative ERA value. yeah.

so the way I was handling rate stats didn't totally make sense for pitchers, because it penalized you for having high IP. I think that ultimately this should get rethought to credit high IP guys and discount low IP guys.

one approach would be to sort by IP for SP (IP is a skill) and wherever replacement lands (50? 60?) treat that guy's IP as 1, and multiply the zscore for ERA and whip by that vector.
