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

32.    Damian Lillard-22.41

Milwaukee Bucks star and future Hall of Famer Damian Lillard makes the cut. Despite this list being dominated by forwards and centers, Damian Lillard is simply too good for PER to ignore. While many high-scoring guards that preceded him got buckets by frequent drives to the rim, drawing free throws, and mid-range jumpers, Lillard often scores by bombing away from outside.

In fact, 45% of his 18.5 career field goal attempts per game have been threes and he's drilled 37% of those shots. He isn't just an efficient bomber either; he is shooting nearly 50% from inside the arc over the course of his future Hall of Fame career. Lillard's elite outside shooting has helped him become one of the most efficient scorers of his era. PER, after all, heavily weighs efficiency, specifically 3-point efficiency.

Moreover, Lillard boasts a sky-high 58.8% true shooting percentage over his career while also averaging more than 25 points per game. Better still, he has a good assist-to-turnover ratio for a high-usage point guard.

All of that helps him rate among the best point guards all-time in PER and even in his age 33 season, he still boasts a PER over 20. With a few good seasons left in him, he could continue to improve upon both his rank in this regard and his legacy in general.
