Look at Wilt Chamberlain. In his 14 seasons, he had 6 with FT% below .500, including .380 when he was 31. DeAndre Jordan, who is still playing, has had a FT% below .500 for his career, including four years below .400. Some of the big guys just don't shoot well from the foul line.His FG% is a staggering 73% while his FT is also staggering, but for a different reason - 46.7%.
