The South Florida Sun-Sentinel (Ira Winderman) reports: Marcus Banks, who has spent his career previous career stops with the Boston Celtics, Minnesota Timberwolves and Phoenix Suns almost exclusively at point guard, exited the Heat’s preseason schedule as a frontrunner to back up starting shooting guard Dwyane Wade, even with his uneven effort in Friday’s 96-93 victory over the San Antonio Spurs. “He’s a combo guard, in my mind,” coach Erik Spoelstra said of the 6-foot-2 sixth-year veteran. “I just look at him as a player. He’s a very good high-pick-and-roll player. He can create, get in the paint for us. “But he also can play some point guard for us.” … By moving Banks to shooting guard, it somewhat reduces the team’s need for second-year Daequan Cook.
