The Mavs are looking similar to their first half in Game 1. They're pushing the pace and rotating properly. Chris Paul has two points and three assists, but is 0-3 from the floor as the Mavs are denying him penetration. His bread-and-butter involves getting inside, so as long as the Mavs can keep a body on him on the perimeter and being physical and collapsing properly on him when he does get in the lane, they should continue to do well against him.
They just have to be mindful that when they collapse on him, they have to keep an eye on the perimeter players like Peja and Mo Pete. One other note on why the Mavs have played well: Tyson Chandler had two early fouls and is out right now because of it. Keep an eye on how things go when he returns.
