Coincidentally, I'm in the middle of a re-read of MoneyBall. I just read the introduction on Bill James. For him, it was the hitting stats that bothered him. For me, it was the pitching stats. I remember very clearly in middle school in about 1986-1987, I would have been 13-14 years old, reading the box scores and league leaders in the paper and just thinking that stats didn't tell you anything about the pitchers. "Joe Blow is 3-2 with a 3.57 ERA." What the heck are you supposed to make out of that? My solution to this "problem" was mainly to zone out any time a broadcaster started blabbing about stats. It wasn't until much later, maybe about 2005, where I learned that other people had similar issues with the stats that I did and had actually done something about it.
