John Hollinger of ESPN and the New York Sun has his own personal statistic for player value: the "player efficiency rate" or PER. Hollinger rates NBA players on the PER and so when he came up with his Least Improved Players, he used PER stats to determine whose performance has dropped this year. Jason Collins made the list, but Hollinger adds that his PER is "the worst of any player in the past two decades".
