The way Orlando Magic president of basketball operations Jeff Weltman tells it, lots of teams were loading up to select Chuma Okeke. The Magic had to make the pick then if he was there guy and could not afford to trade down.
That would not stop rampant rumors that Orlando should have traded down. The team waited to leak its pick to Adrian Wojnarowski of ESPN until just before Adam Silver announced it on the stage. That actually slowed down the draft in some way — yes, teams keep track of who is picking who through reporters leaking information by all accounts.
