It didn't look like Wade traveled. It's still right that he got called for a phantom travel after all the phantom fouls he benefited from.
He clearly traveled, they just usually let him get away with that. You cannot move your pivot foot after you pick up your dribble. They let players do that hop, which is illegal, when they are moving towards the basket, but he did it to move backward to get behind the 3 pt line. Nice try Wade.
