 Chamberlain's impact on the game is also reflected in the fact that he was directly responsible for several rule changes in the NBA, including widening the lane to try to keep him farther away from the hoop, instituting offensive goaltending and revising rules governing inbounding the ball and shooting free throws (such as making it against the rules to inbound the ball over the backboard). Chamberlain, who reportedly had a 50-inch vertical leap, was physically capable of converting foul shots via a slam dunk without a running start (beginning his movement at the top of the key). When his dunks practically undermined the difficulty of a foul shot, both the NCAA and the NBA banned his modus operandi. In basketball history, pundits have stated that the only other player who forced such a massive change of rules is 6' 10 "Minneapolis Lakers center George Mikan, who played a decade before Chamberlain and also caused many rule changes designed to thwart so-called" big men ".
