# of foul balls with 2 strikes? I'm looking for that "pest" factor. I wish we could quantify # of starts over a better, younger, player. Difficult to do though. How about a calculation for reverse VORP? The gritty player in question is assumed as an average replacement-level player and his rVORP would be the inverse of the VORP of the more talented, higher-ceilinged player he's blocking. I would also consider introducing "loss-shares." Thoughts?
