FIBA is cool with players blocking shots that are on the rim, and wants the NBA to feel the same way. From ESPN:  “The secretary general of FIBA, the governing body of international basketball, would like to see the NBA change its goaltending rules to allow players to knock the ball off the rim. The official, Patrick Baumann, made the comment during a lunch meeting with eight selected American and European journalists Thursday before the final two quarterfinal games at the FIBA World Championship. FIBA rules allow players to knock the ball off the rim after it touches the cylinder, whereas in the NBA that would constitute a goaltending violation. Baumann also said the chances of Great Britain being awarded a spot in the 12-team field for the 2012 Olympics will be made next March during a meeting of the FIBA executive committee, but will be contingent in large part on the British Basketball Federation’s road map toward building the growth of the sport for the long term. FIBA will be instituting two rules changes at the conclusion of this tournament, abandoning the trapezoid lane in favor of an NBA-sized rectangular lane, and moving the 3-point line back by a half-meter (19½ inches) from its current distance of 20 feet, 6.1 inches.”
