Box Score Geeks says 46 Wins is Realistic
The analytic guys over at Box Score Geeks (Formerly TheNBAGeek) picked the Pistons to finish 4th in the East, 10th in the NBA, and have 46 wins as a "realistic" option, with an optimistic 53.8! It's worth the read, especially if you want some crazy next level statistics like decimal positions (i.e. Rodney Stuckey's position is '1.6')
