What we need to do, is to have someone write an article on how to do the research on which pitch FX website for past games, and then create a Xcel spreadsheet that would record the bad calls - who it happened to, who was catching / pitching, the game situation (outs, score, base runners), where the pitch was per normal strike zone and the now expected lefty and righty strike zones (on the line, in the zone, just outside) and etc...
There are enough guys on this site that we all could then do the work of recording the results for a couple months, and we would have doubled or triple checked our work for each game for the past 3 to 5 years.
Then we would all know the truth, and how rampant this is.
