who did the free throw line dunk first
Slam dunk In the 1950s, Jim Pollard[26] and Wilt Chamberlain[27] had both dunked from the free throw lineâ€”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.[27] 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.[28]
