No. But we're talking about greatness over a career, and consistently carrying a team.. And I just haven't seen any ball handling players that I consider great who have had a poor career FT percentage. And I consider anything under 80% poor by NBA standards.
What about Isiah Thomas? Was he a great ball handling player? Not by your standards.
Career FT% = 76%
His first 3 years in the NBA, Isiah averaged 71.5% FT
Playoffs FT% = 77%
