He talks about Yao at the beginning and you should be able to skip ahead if you don't care about him.
Morey makes a few good points about how 90% of the guys will go through sign & trade, players want to get paid as much as they possibly can and they won't just leave $30 million on the table. The reason all of the free agents are setting up meetings with all the teams with extra cap space is to create the leverage to go the s&t route.
He says at the end of the day, players will look at all their options and could come to the conclusion that they would want to play for a team like the Rockets (or Mavericks or any winning team without cap space) that will operate with $20+ million more than the teams with space and already have a winning roster in hand.
Miami and other "cap-clearing" teams will use up all of their remaining cap room on the big names and will go into the season with around 6 to 10 "minimum contract" guys. He says that he's never seen a team with that many minimum contract players compete for a championship.
I probably left some things out. It's worth a watch to see how the mind of an NBA GM works and sort of gives you hope for your team, even if you don't have cap space.
