As for Jeter's difficult double play, it was literally the NEXT pitch, so your theory of increasing the pitcher's workload etc. is entirely moot. However, I understand that is an isolated incident, but it's the incident that we're discussing.
Furthermore, the point was that UZR is bogus because the first missed DP would show up in those stats even though the second, and completed, DP erased any potential ill effects from the error. As far as I know, UZR does not deal with a pitcher's level of energy or stress. However, again, I don't mess around with these dork stats but it seems you're getting a little off topic as it relates to UZR.
