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

67.    Jonas Valančiūnas-20.63

Admittedly, even I was surprised to see Jonas Valančiūnas in the top 75 in all-time PER, but he is exactly the kind of player that tends to do well in this stat. He frequently shoots in the mid- to high-50s from the field, is an above-average free-throw shooter and has even expanded his range to three in recent seasons. 

While he is a low-volume 3-point shooter, he has shot above league average the last five seasons, and the added weight of threes helps him rate highly in PER. To his credit, Valančiūnas has been known for some monster performances since he can fill up the stat sheet as an efficient scorer, a terrific rebounder, and a player who can rack up blocks with his 7'6 wingspan. 

Despite that, he can be overrated for that reason and is probably on the lower end of the list of starting centers. That makes the thought of him being 67th on this list perplexing and gives further weight to the criticism that PER overrates big men, with Valančiūnas being a case and point in that argument.
