Idk why Piazza gets shit on.
Everyone acknowledges him as the best offensive catcher.....yet he's never top 3 in these rankings, just because he wasn't good at throwing out runners.
All of the advanced stats say he was great at everything else a catcher does (blocking, pitch-framing, etc).
Add that to being an offensive MONSTER....and you get ranked behind guys like Carlton freakin' Fisk.
