The Miam Heat open their preseason schedule in advance of their attempt at a three-peat Monday vs. Atlanta. But they'll be short on some frontcourt depth when they face the Hawks. Missing Greg Oden is to be expected. Even after the Heat signed the former Trail Blazer he's not expected to be back in game shape for a long time. He's on that "indefinite" timetable. Haslem had surgery on a torn meniscus this summer.
