I'm not with you on this one FGWM. Almost every stat, and certainly every baseball stat, has got room for the exercise of discretion and is faulty to some extent. That doesn't mean that we shouldn't use them (otherwise there would be no FB), all it means is that we should give more weight to certain stats than to others.

ZR has got some use but I don't think that you should, on the basis of ZR alone, say that Andruw Jones or Pudge are poor defensive players. I don't give much weight to ZR.

While it's true that statistics are open to interpretation, some statistics are abominations to mathmatics and logic. I've explained numerous times why defensive statistics are fershit. If a statistic is a simple mathmatic formula and mathematically sound it is simple to buy into. Batting Average is a perfect example of this; it is a straight ratio. In contrast, OPS isn't. Instead, it is the addition of two fractions with different denominators without creating a common denominator, so it's validity is zero. Just to clarify - A player with an OPS of 1.000 doesn't perform in an arithmatically predictable manner better than someone with an OPS of .800. The end value isn't a mathmatical calculation.

People can show me as many formulas as they want, and I really don't care. They should know as well as I that you can manipulate numbers to say just about anything you want. I could easily plug numbers into a formula and come up with some arbitrary number that is assigned a positive or negative connotation.

I enjoy baseball statistics as a whole, they are the backbone of the game, as long as they are used appropriately, and are mathematically significant to the analysis they are being used to support.

You're absolutely right. I've said before that it's a gimmick invented by James to sell the STATS Inc. services. He didn't have an opinion that anyone would buy but he had stats to sell. When people could get the stats from MLB or other providers, he had to come up with something new - so he mashed a bunch of numbers together and voila, a new product. Throw it in the basket with WinShares, MLV, OPI etc. and go to the checkout.

I also love how he guards (some of) the formulas that he uses but still wants us to take his stats seriously.
