36.    Clint Capela-22.12

Atlanta Hawks center Clint Capela is likely the most unlikely player to crack the top 40 players on the list. In fact, he is the only non-All-Star to appear in the top 75, which is hard to do considering that his career PER of 21 suggests that he should have been an All-Star several times during the first 10 seasons of his career. Instead, according to this metric, he may be one of the best players to never make an all-star team in NBA history. 

When looking at Capela's numbers, aside from his strong rebounding numbers, nothing jumps out at you. Be that as it may, he has been averaging 12.2 points, 10.7 rebound, and 1.5 blocks over the course of his career. Given his role as an athletic big man who can finish around the rim, it's no surprise that he has a sizzling 62.1 career true shooting percentage. 

Those strong numbers are the reason why he has a 22.1 PER and that is unlikely to change much in the near future. He is just 29 years old and has had a PER over 20 for the last eight seasons. Centers tend to age well so it is possible that he has another four or five seasons at this level, ensuring that he doesn't drop off this list.
