The South Florida Sun-Sentinel (Ira Winderman) reports: The Heat seems to be hitting its stride with Udonis Haslem having settled in at center and Mario Chalmers at point guard. In addition, Chris Quinn has morphed into Jason Kapono.  The question now is whether there is room for anyone else in what has grown into a tight, comfortable rotation, with Haslem, Michael Beasley, Shawn Marion, Dwyane Wade and Chalmers as the starters, and then Quinn, Yakhouba Diawara, Daequan Cook and Mark Blount off the bench.
