<P> In the 1950s , Jim Pollard and Wilt Chamberlain had both dunked from the free throw line -- 15 feet from the basket . Chamberlain was able to dunk from the free - throw line without a running start , beginning his forward movement from within the top half of the free - throw circle . This was the catalyst for the 1956 NCAA rule change which requires that a shooter maintain both feet behind the line during a free - throw attempt . </P>
