Comments on: A Model of Inefficiency http://www.detroittigersweblog.com/2005/10/model-of-inefficiencyphp/ News, views, and analysis on the Detroit Tigers and baseball Fri, 10 Feb 2012 20:06:14 +0000 hourly 1 http://wordpress.org/?v=3.3 By: SJC in Detroit http://www.detroittigersweblog.com/2005/10/model-of-inefficiencyphp/#comment-1115 SJC in Detroit Thu, 01 Jan 1970 00:00:00 +0000 http://test.detroittigersweblog.com/2005/10/08/model-of-inefficiency.php/#comment-1115 Thanks for crunching numbers to back up what I've been telling my sons and the other players I coach -- the Tigers are inefficient. I'm not a big believer in "productive outs" and bunting to move up runners but, on the other hand, there are times when you just need to put the ball in play and make the most of your opportunities. Watching the Angels is quite a contrast. Your opening example sounds like you were listening to me several times at Comerica this past season. Oh, and this article gives me another chance to point out to my kids the proper use of math in general and statistics in particular -- thanks.

Just a quick comparison, TBW (I included HBP as well) has a .941 correlation with runs scored. REA has only a .702 correlation. REA and TBW have a .421 correlation between them. Obviously this is only looking at linear relationships between the variables, but I do think it demonstrates a usefull point. The end goal of an offense isn't to get a high percentage of it's base runners home, the end goal is to score alot of runs. <br> <br>While being an efficient offense is a good thing (just ask Boston) the lack of correlation between TBW and REA implies that maybe it's not the most important thing (just ask Cleveland).
