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

37.    Dolph Schayes-22.09

Legend Dolph Schayes was one of the league's first stars after the National Basketball League and the Basketball Association of America merged to create the NBA. Schayes made his debut in 1949, four seasons after the NBA first started and played for 15 years, which was unheard of then, with other stars such as George Mkan only playing for nine years. Schayes's longevity served him well and he spent the entirety of his playing career with the Syracuse Nationals, now the Philadelphia 76ers.

While Schayes isn't a household name any longer, he actually has more win shares than other Philly greats such as Julius "Dr. J" Erving, Charles Barkley, Allen Iverson, Wilt Chamberlain, and Joel Embiid. That is quite the who's who of NBA legends and shows just how good Schayes was. He was a steady scorer who lived at the free throw line, averaging nearly eight attempts per game and shooting at least 89% on free throws a staggering four times. 

Schayes was also a dominant rebounder, grabbing 16.4 boards per game in his second season and 12.1 per game over his career. Of course, Schayes, like pretty much every player from the NBA's first two and a half decades, couldn't shoot efficiently.

In fifteen seasons, his highest field goal percentage was just 40.1% and his scoring and rebounding numbers were inflated by the faster pace but PER takes that into account and his 22.1 PER is good enough for 37th all-time.
