66.7% is brake even. anything over is worth it, anything under is not. CORRECT? On average, correct. Obviously, there are situations where a SB is more valuable and where a caught stealing is more costly, so it's not a steadfast rule. Some players might boost their SB by stealing 3B with 2 out (not much value at all). Some players might only get caught stealing when trying for 2B with 2 outs (not as bad). I'm sure you could quantify actual value and costliness (is that a word) of a particular player's steals and find who adds teh most value to a team in the league. I just might have to look into that http://forum.brewerfan.net/images/smilies/smile.gif Batting Runs is just another linear weights formula (there are several but they are all very similiar), which is found by performing multiple linear regression on actual team data. While not perfect (again, all the numbers are for average situations) I like it because it's simple and straight foward. Here's a nice article on the subject: Batting Runs and Linear Weights
