Walk Like a Sabermetrician: Win Shares Walkthrough, pt. 5

Using his Walk Like a Sabermetrician blog, USPatriot has recently posted his 5th part to examining the Win Shares method from start to finish. Why is he doing this? From Part 1:

The reason why I am doing it is so that I can comment on what I think are the flaws in Win Shares at the actual stage of the method at which they occur. This way it is easier to see what I mean rather then running through the method, then making a laundry list of complaints at the end.

The rest: Part 2, Part 3, and Part 4.

I also recommend checking out USPatriot’s archives, as there’s other great material that hasn’t been linked to before via BTF. In fact, I just realized USPatriot had a blog when I read Studes’s Ten Things I Didn’t Know A Couple of Weeks Ago, in which he provided a link to USPatriot’s study on Ranking the Leadoff Hitters.

Add reading the Walk Like A Sabermetrician archives to my weekend task list, which also includes reading the August “By The Numbers” and watching Seinfeld Seasons 5 and 6 (currently on The Non-Fat Yogurt), and I should be all set.

I didn’t know Patriot had a blog, either.

I find the rate stat series interesting so far, as is the leadoff rankings piece. I’m going to post some comments on the blog itself.

I too an surprised—and delighted—to learn that Patrio has a blog.

This Win Shares series is a good summary of WS’s conceptual flaws. I agree wholeheartedly that the “zeroing out” is a real problem; it’s something I noticed the first time I read the book, and if I notice it, you’ve done something wrong.

Patriot makes a good point I hadn’t considered when he discusses how WS splits up credit between pitching and fielding by looking at team K/BB/HR rates instead of individual. It might be better to define each pitcher as being his own “team” for the purposes of that step.

I’m just delving into the rest of the blog now, but there’s some great-looking stuff here.
