nERD: -11.3

In his ninth NBA season, Antoine Walker spread his inefficient style of play across two teams -- those teams being the Atlanta Hawks and Boston Celtics. In February, after yielding 20.4 points per game in 53 games with the Hawks, Walker went into Beantown and averaged just 16.3 points.

Overall, Walker's box plus-minus of -0.4 and -1.4 offensive win shares were not satisfactory. Even as Boston made a push to the playoffs, they failed to make it out of the first round.
