For arguments sake, please address this and give me a win difference attributable to all these aspects. I'll give you my estimates in parentheses.
1. Danny's defense vs. Rendon's at 2B (+1 Danny)
2. Rendon's defense vs. Zimmerman's at 3B (+1 Rendon)
3. Zimmerman's defense vs. LaRoche's at 1B (even)
4. Danny's bat vs. LaRoche's bat (+1.5 LaRoche)
So a total of half a win more with a Zim, Espy, Desmond, Rendon infield rather than LaRoche, Rendon, Desmond, Zim.
I would have Danny's defense is better than +1 over Rendon.
I also think ALR is a much better 1b than Zim mainly due to the experience.
Are you talking Danny's bat recently? If so ALR far superior.
