10.    Kevin Durant-25.20

Phoenix Suns superstar Kevin Durant is still playing incredibly well in his 16th season, allowing him to maintain his already sky-high PER. The four-time scoring champion has been one of the game's most prolific scorers since entering the NBA in 2006 with the Seattle Supersonics and later the Oklahoma City Thunder.

For nine seasons, Durant tore up the league as a member of OKC, averaging 27.4 points on 60.5% true shooting, 7 rebounds, 3.7 assists, 1.2 steals, and 1 block. He later left and signed with the Golden State Warriors, joining up with Klay Thompson, Steph Curry, and Draymond Green to form a super team.

While that was a controversial move, it did result in three straight NBA Finals appearances and back-to-back championships in 2017 and 2018, with Durant being named Finals MVP. Durant left in the summer of 2019 and joined the Brooklyn Nets, though he missed an entire season with an ACL tear.

Since then, he has battled injuries but has maintained a high level of play even into his 30s. In fact, he is currently averaging more than 27 points per game at age 35, something that was once thought impossible. If he continues to age at this impressive level, he might not see much if any slippage when it comes to his career PER and his overall place in the greatest players of all-time discussion.
