This post has become old news, and I'm not sure anyone is checking in here anymore, but just in case I wanted to throw this in: First of all: "There wasn't any analysis. It was raw numbers." You're absolutely right. The way I laid it out made it sound like I was accusing you of drawing a conclusion AND, on top of that, that your conclusion was wrong. Neither of those is true, and I owe you an apology for implying such. What I meant, and should have said better, is that conclusions that could be construed as IMPLIED by the raw data (e.g. that pitchers got a whole lot better in the last 20 years) would certainly be incorrect -- the subtext explains the behavior of the numbers, and it's critical not to reverse that process. You never did that, but the comparison of Trammell to Ozzie DOES, in a way, do that. In short, grum and yerfatma are both correct, and I am not a numbers basher per se. I love playing with them myself, and I do see the value in them that grum described. However, we (baseball fans of the world) seem to be easily led down the slippery slope of statistical "analysis" that puts the cart before the horse and causes some of us to make comments like "Well, if Mazeroski belongs in the Hall, and he hit X, then..." I get sucked into that argument, too, and it's a hot button topic for me because, well, I'm not that smart and I'm easily beguiled with numbers. Trammell may belong in the Hall -- I'm rooting for him, in fact -- but he doesn't belong simply by virtue of having better stats than Ozzie or anyone else who is already there. "Even if you watch a batter play an entire season, you still don't have a full idea of how good a hitter he is." This is where I think you ARE incorrect. The questions that you pose all address issues with a player's statistics and how they can be deceiving, but not how watching a player can deceive you. Here is why, in my opinion, numbers are important. Raw numbers, taken in context, positioned with answers to the questions you have quite appropriately posed, have a very good likelihood of representing the player's true ability. It's not true with Ozzie, it's not true with Jeter, it's not true with Mazeroski -- on and on -- but it is true often enough to justify their use. Nobody gets to see every player every day, and as you correctly pointed out, nobody alive saw Dan Brouthers, so stats, along with perhaps news articles and general "reputation," make up the best estimate of a player's quality.
