B...I found your site thanks to Baseball-Reference.<br /><br />Both David Freese and Chase Headley are above average 3rd basemen.<br /><br />I am aware of the fact they use UZR in their WAR calculations, I don't know how they measure Dewan Plus/Minus where as I do with UZR.<br /><br />The UZR/150 when you stretch a player's UZR out to 150 games (average games played for a everyday player)<br /><br />Fangraphs uses basic UZR to calculate WAR, not UZR/150.<br /><br />I enjoyed the post though, very sound reasoning, it's hard to find mathematically sound amateur sports writing. I look forward to more of your posts.Dillonhttps://www.facebook.com/pages/Simply-Sports/117230861629395noreply@blogger.comtag:blogger.com,1999:blog-5325217338696855922.post-47137933227045154322011-11-13T08:35:51.783-08:002011-11-13T08:35:51.783-08:00Showing Headley as the sturdier player was one of ...Showing Headley as the sturdier player was one of the points of this post. Because UZR is used in Fangraphs' WAR calculation I went with the Dewan plus/minus metric to demonstrate their differences defensively.<br /><br />So much for my methodology.<br /><br />You may not have meant to but you bring up a great point regarding defensive metrics. There is disagreement among writers I respect on which is the best metric to use for evaluating defense. I'll likely treat that in a future post.<br /><br />Thanks for reading!Mikehttps://www.blogger.com/profile/12834783703709709964noreply@blogger.comtag:blogger.com,1999:blog-5325217338696855922.post-6066251289182965822011-11-12T16:16:12.627-08:002011-11-12T16:16:12.627-08:00If you wanted to measure defensive capabilities, U...If you wanted to measure defensive capabilities, UZR is a better way to go. In that matter, Freese is actually the better defender but extremely considerably margin. Since Freese hasn't played 150 games in a season yet I'll use the UZR/150G<br /><br />Freese: 1.1 career, 3.9 in 2011<br />Headley: -12.9 career, -10.4 in 2011<br /><br />In this matter, all you get in Headley is a more sturdy player, which is why he has the higher WAR. Looking at DWAR, Headley loses again at -1.1 career compared to Freese's +0.8.Dillonnoreply@blogger.com
