Uncle Mu's habitual movements not only attracted imitation, but also caused controversy, while the media counted the number of times he shook his fingers every season. For example, from 1999 to 2000, Uncle Mu shook his fingers 242 times and blocked 269 times this season. Many NBA players, including Jordan, regard Uncle Mu's action as a provocation and frequently protest to the league. In the end, the NBA had to make a rule that "waving fingers is a technical foul and should be punished", but soon, the league went back on its word for three reasons:
First, Uncle Mu shakes his fingers not at his opponent, but at the sky and the fans, and often with his back to his opponent; sequence
Secondly, fans seem to like this iconic action of Uncle Mu very much. It is hard to believe that Uncle Mu would be so "naughty" because of his kindness and sincerity.
Third, Uncle Mu's finger shaking has become one of the symbols of the NBA.
At this point, the NBA has the only "privileged case". As long as it's not directed at the opposite hand, Uncle Mu enjoys the privilege of shaking his fingers. Of course, for the current NBA, no one else has such privilege, and no one dares to be so arrogant.
