Adam Silver attended the Portland Trail Blazers' game on Tuesday against the Dallas Mavericks.

Neil Olshey and the Blazers are rebuilding after losing LaMarcus Aldridge to the San Antonio Spurs in the offseason.

Silver was asked if he was surprised by all of the changes the Blazers made.

"I don't know if I was surprised," said Silver. "Paul Allen's been in this league a while now. He knows you have to go through a rebuilding process. At the same time, I appreciate that they're rebuilding in a way where they're not bottoming-out in any way. Fans still want to see competitive teams on the floor, but it is necessary to rebuild at certain times to sort of assess where you are. I think they're doing a good job."
