TangoTiger has a neat project at BaseballStuff.com. He wants fans to evaluate different attributes of players defense based on what you've seen at the ballpark and on television. I think this is a great idea. Collections of humans can act like a giant multi-processor computer, where each processor is doing the same task in a slightly different way. The aggregate of these opinions is usually the right answer. (That's why football point spreads are so good. They are set by the betting of an enormous group of experts.) If you've seen players enough that you have an opinion about their defense, stop by and fill out the survey. I can't wait to see the results, and how they might compare to other statistical measures of defense.
