The Mavs scored 12 points in the paint in the first quarter while also attempting 11 three-pointers. Normally when a team scores that many points in the lane, you don’t see as many treys in one quarter because so many shots come at the rim instead. But Dallas truly played “MoreyBall,” a nickname for Houston GM Daryl Morey’s preferred brand of basketball that encourages nothing but layups and three-pointers.
