I’ve been writing about baseball online for four years, and early on, I learned I needed to work hard to create anything meaningful. A few years ago, I killed a weekend creating a stat I dubbed, “Runs Accounted For.” It looked at a player’s run and RBI totals compared to his team’s run total and, as I later learned, was more or less a simplified version of Bill James’ work, Runs Created. I didn’t know this when I posted my piece (I hadn’t read a James book up to this time), and proudly, naively, I submitted a link to Baseball Think Factory expecting to be applauded.
The response I got is fairly typical for anyone who creates a new baseball metric and is one reason I don’t devote much time inventing stats.
