There is some precedent for this kind of nonsense. The NCAA banned the slam dunk in 1967 because Kareem Abdul-Jabbar was so unstoppable that they wanted to slow him down. The NBA allowing the zone in 2001 was done so teams could double and triple-team Shaquille O'Neal before he got the ball because he was so impossible to guard.
I'm definitely not saying they should do this, of course, especially in the Olympics. Crippling dominant teams and players to promote competitive balance in team sports tends to be a more practical measure to keep fans of the crappier teams interested and paying.
