Daryl Morey tweeted support for the Hong Kong protestors. The owner of the Houston Rockets disapproved and said they are about basketball, not politics. They don't want to offend anyone. Especially not a big market like China. which has a "special relationship" with Houston since Yao Ming. Nice little NBA business you've got there. It would be a shame if anything happened to it.
It will be interesting if Houston fans have diminished interest in the Rockets going forward.
Update: The NBA has weighed in that they don't want to be political about such things. I recall, however, that it was perfectly okay for LeBron James to announce that no one would be going to the White House no matter who won the championship, and players and coaches have been saying anti-Trump things pretty regularly. They also let Enes Kanter be very political about Turkey (which he is courageous for doing, BTW). I guess there just aren't enough potential fans to buy shirts in Turkey.
