Ok, how about this: First, WTF is the NBA doing monitoring every NBA announcer and complaining during the game to the announcer if he says something the NBA does not like? Announcers are employed by the NBA team, so you can bet that they take heed when the NBA calls.
Secondly, look at the case of Houston coach Van Gundy. According to Donaghy, who was an alternative referee in that series, the referees received an e-mail from the league office pertaining to Yao Ming, and they discussed Yao at the morning meeting....since Cuban was upset at Yao's illegal screens, the office made sure that we were to watch him closely. We were also instructed to watch his footwork and look for traveling violations. However, contrary to league policy, the supervisor of referees for this series (with whom Van Gundy had built a relationship) passed this information along to Van Gundy. The supervisor of referees was providing inside information to Van Gundy....and told him to make sure Yao avoided setting illegal screens because the referees would be watching closely. But then Van Gundy made a mistake - he slipped up and during a news conference and told the "New York Times" and "Houston Chronicle" that he had "inside information" that he was getting screwed. In order to cover its tracks the NBA sent out a news release stating that Van Gundy apologized for his remarks about inside information, and that there was NO PROOF that an NBA referee had any communication with Van Gundy pertaining to the game.....eventually the NBA admitted that both Stu Jackson, the NBA's Executive Vice President, Basketball Operations, and Donnie Vaden, the supervisor of referees, had spoken with Van Gundy during the series.
