The 75 greatest players in NBA history, ranked by Player Efficiency Rating (PER)

51.    Adrian Dantley-21.51

Hall of Fame journeyman Adrian Dantley played for seven teams in his fifteen-year NBA career. Unfortunately, that led to him being severely underrated by fans in the greatest player rankings. Actually, he failed to make the NBA 50th anniversary team as well as the 75th anniversary team.

That is despite his averaging more than 30 points four straight times in his career. Only a handful of players have ever done that and many of them are much higher in the GOAT discussions. Dantley wasn't just a high-volume scorer; he was among the most efficient players in league history, with a 61.7 true shooting percentage to go along with 5.7 rebounds and 3 assists.

That type of scorer and shooting ensure him a place near the top in PER and he is on the cusp of being a top-50 player all-time. Be that as it may, Dantley still seems destined to be underrated and aside from him bouncing around the NBA, most of his best seasons came as a member of the Utah Jazz in the pre- and early John Stockton-Karl Malone era. Too bad.
