The eight-time NBA champion and Hall of Famer is without a doubt one of basketball's all-time greats.

In 1962, he was drafted both by the NBA's Boston Celtics and the NFL's Cleveland Browns, in the seventh round. He completed a brief stint at the Browns' training camp that year but decided to focus solely on hoops and his future with the Celtics. The decision seemed to work out well for him.
