You're missing the meaning. The idea isn't to be removing those factors, it's to be able to properly see how much they help or hurt players. Wouldn't it be real nice if a GM knew what taking a player like Dante Bichette out of Coors Field would do before signing him to a nice contract? Or how about what would happen if you took Chan Ho Park out of Dodger Stadium and put him in Arlington? We already know which players are good and bad. Albert Pujols and Alex Rodriguez are good no matter what numbers you're trying to use. Neifi Perez and Jose Macias aren't. The metrics are more designed at trying to separate those guys in the middle of the pack, where ballparks and other things the players have no control over can make a much bigger difference. Ok, let's run with this. Jamie Moyer has 230 career wins. Sandy Koufax had 165. Now I'm not going to insult you and try to say that your logic would mean that Moyer is a better pitcher than Koufax. I know you wouldn't buy that. But you know Koufax is a better pitcher because you look past just the wins. You take a look at the ERA, you take a look at the difference in games pitched. That's all these metrics are doing. They're grabbing all the pertinent information and putting them into nicer numbers. They certainly aren't ridiculous. They're just how you separate guys like Juan Pierre (career .301 batting average and not a very useful player) from Joe Cronin (career .301 batting average and an extremely useful player). What is it you "old school" guys like to talk about? The "little things"? Well the little things like ballparks, league scoring environment, etc... all add up to be pretty important when valuing a player correctly. It's how you know Yaz was fantastic in 1968, and how you know Three Finger Brown isn't exactly Pedro Martinez, despite the 2.06 career ERA to Pedro's 2.80. I think it's time to start giving a little more credit to these metrics than you currently do. I think he's including those "old Time" stats and not getting rid of them, that's his point. I see nothing wrong with using all the resources available.
