Don't know how big the differential is in practice, but that kind of logical inconsistency is a strike against the formula in my book.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5394137.post-69559209642383399452011-04-23T10:20:50.231-05:002011-04-23T10:20:50.231-05:00It is certainly true that there should be corelati...It is certainly true that there should be corelation between run differential and wins. The reason that it isn't as clean as The Geek suggests is that you don't get extra wins for winning 8-2 as compared to 3-2. If you happen to have a rather inconsistent team where you put up big scores sometimes and little or nothing a lot of other times, you can have a rather nice run differential Jim Hnoreply@blogger.comtag:blogger.com,1999:blog-5394137.post-10189813930133402612011-04-23T08:33:59.254-05:002011-04-23T08:33:59.254-05:00Hey John,

The fact that having a lineup balanced between getting on base and hitting produces the most runs does not mean that is true for individual players.<br /><br />Its not hard to see that having a player who gets on base a lot batting in front of player who hits a lot of home runs is going to produce more runs than two players who are average at both.
