Jonathan Feigan was just on AM 1300 in Austin and he said the Rockets would be holding a press conference sometime today before the draft to announce the will select Ming. I didn't catch a time, just that it would be later today.
Heard the same thing on ESPN Radio 103.3 here in Dallas. He said it would be in 30 minutes. That was at 9:30CST, so it sounds like about 10:00am they will be holding the news conference.
