PORTLAND — The Rose Garden reception for Joel Przybilla and Dante Cunningham was warm and appreciative and chock full of admiration. The Trail Blazers weren’t quite as welcoming. Meeting their former teammates for the first time since they were traded away nine days earlier, Portland players were merciless amid the reunion. Their first and second units dominated. They got production out of everyone who took the floor. And in allowing the fewest points they have all season, the Blazers crushed the Bobcats, 93-69. “We played defense to try to keep it close,” Blazers forward LaMarcus Aldridge said. “We finally found our rhythm in the second half. That was big for us.” Yes, the first 24 minutes of Saturday’s game was certainly no study in aesthetics. Despite leading 40-35 at the break, Portland finished the first half shooting 37 percent. Charlotte, meanwhile, was at 39 percent. It was even uglier from behind the 3-point line, in which the Blazers were 2 of 11 and the Bobcats 1 of 6.If Portland head coach Nate McMillan delivered an inspiring locker-room speech at halftime is unknown, but the Blazers morphed into a different team in the second half. That was much in part due to the second unit. Point guard Patty Mills made just four shots Saturday, but all came from beyond the arc as he finished with 12 points. Brandon Roy played just 20 minutes Saturday, but he capitalized on it by by scoring 10 points.
