Break even point for runs allowed by position

[Roscodog]

I don't know the #'s or have anything to back it up other than the experience of playing the game, but if the offensive #'s are the same I'll take the 2 at SS and 4 at 3B anyday of the week.

Each range factor at SS is worth about 20-25 errors. Each range factor at 3b is worth about 8-10 errors. An error is defense is basically the same as a hit on offense -- 25 one base errors over the course of a season is basically the same as 25 singles or maybe .35 points of obp and slg.

A website I reference for comparing defense ratings with expected offensive OPS production differences is:
http://andrew-stevens.tripod.com/index/stratfield.html

I haven't found any errors in the math or theory behind it. There are some assumptions, but they seem valid.

Using his analysis, the big difference in 3B will equate to about a .174 difference in offensive OPS. The difference at SS equates to about .141. So, based on that analysis, if the offense is the same between the batters involved, the defense of the 1e10 at 3B more than makes up for the difference at SS.

Stevens' article looks interesting, but Dean's classic treatise -- when subtracted from the NERP in Diamond Dope's analysis will give you a great idea of a player's relative run value to a team.

bump, I reference this thread and almost couldn't find it.

Sorry for bumping an old one but the link to the defensive study is quite useful

[pikesvilleal]

I have no idea about empirical studies, but Troy Tulowitzki's defense and all the DPs he starts was worth the price even though his offensive production is pathetic.

Each range factor over 1:
SS: Add 21 to errors -- 3e20 == 62 (2*21 + 20), 2e14 == 35
2B: Add 18
3B: Add 9 (4e16== 43)
1B: Add 6

This is a rough est, as it doesn't completely show SI** that you get more of in 3 and 4 range.

The DP factor isn't calc'd as well this way, though that's generally a pretty small piece of the equation. I believe Dean's chart is most precise.
