One of the Pistons’ biggest strengths this season has been their depth. It’ll be put to the test over the next few games. The Pistons will be without guard Avery Bradley for at least a week, as his groin injury and adductor strain hasn’t improved, despite missing the last two games. “He’s going to be shut down for at least a week,” coach Stan Van Gundy said. “We’ll go at least seven days and then week to week. “It’s similar to a sports hernia — it’s not that, but the symptoms are the same.”
