The Detroit News (Chris McCosky) reports: Calling him a “welcome addition,” coach Michael Curry made official Saturday what he’s long been hinting at — Amir Johnson, as of now, is the Pistons’ starting power forward. “Amir does things without having to have the ball,” Curry said. “He’s able to pick up baskets through his activity, by running the floor and playing off the other four guys. He does all the intangible things, and through that he’s able to create offensive opportunities for himself.” How long Johnson holds onto the spot is completely up to him.
