over 600 at bats, the difference between a .275 hitter and a .300 hitter is 15 hits. a guy who hits .300 over his career is a better hitter for average than a guy hits .275 over his career. within a season, i wouldnt be willing to say that. you seem pretty smart. you should read this book. I think I have ADD. I bought Curve Ball 4 months ago, and tried to start it, but couldn't make it to page 20. Maybe once I've been in school a bit and my mind is working again I can try it again on a break. It gets kind of repetitive towards the end, but I really liked it. It kind of makes you wonder about baseball when you realize how possible it is to do everything right and lose anyway, and vice versa.
