MEMPHIS, Tenn. — The Atlanta Hawks were in the midst of a furious fourth-quarter rally and Memphis Grizzlies coach Dave Joerger had to try to stop it. So Joerger turned to point guard Mike Conley — a little earlier than he planned — and Conley responded just like he has in recent weeks. Conley finished with 21 points and 13 assists and Zach Randolph added 18 points and 12 rebounds to lead the Grizzlies to a 108-101 victory over the Hawks on Sunday night.
