The Mavericks used the first half of their 118-71 win over Chicago as a chance to show their regular preferred rotation - at least as it stands now.The starting unit was the same as it was for the preseason opener: Dirk Nowitzki, Harrison Barnes and Wesley Matthews on the front line with guards Seth Curry and Dennis Smith Jr.Off the bench was Nerlens Noel, Barea, Harris, Ferrell and Dwight Powell.Those 10 appear to be the rotation players at this point.It was unclear how many of them would travel to Orlando for Thursday's second game in as many nights.
