by Bob Timmermann
Phil Birnbaum has a link to an article that Bill James has submitted discussing the peformance of the Arizona Diamondbacks. You should give it a read if you are interested in seeing if anyone can make sense of the 2007 regular season in the National League. James is trying to examine whether or not a team like Arizona is more likely to improve or regress in the following season.
