Luka Doncic takes on Ja Morant. They probably won’t defend each other. Memphis is coming off a tough win over Houston on the road. Last season, the Mavs won the last three in this series and covered with ease. This is an improved Mavs team with better defense thanks to the additions of big men Christian Wood and Javale McGee. Memphis is missing Jared Jackson Jr. up front and defensive stalwart wing Dillon Brooks is hampered by a thigh injury.
