Continuing with the discussion on adjusted plus/minus, below is a presentation that Wayne Winston made at the New England Symposium on Statistics in Sports last September on player and lineup analysis in the NBA.  Wayne Winston is a professor at Indiana University's business school and the developer of the original adjusted plus/minus system (the Dallas Mavericks pay him close to six figures for his services).  It's a half hour long and very informative, a very good starting point for future discussions of the adjusted plus/minus in soccer.
