The South Florida Sun-Sentinel (Ira Winderman) reports: The biggest decision for the Heat might be one that is due two days before it exercises the No. 2 pick in the June 26 NBA Draft. The opt-out window for forward Shawn Marion closes at 6 p.m. June 24. By then, he must decide whether to play out the final season on his contract, at $17.8 million for 2008-09, or become a free agent July 1. The timing is no coincidence. In extending Marion a six-year, $80 million contract in 2003, the Phoenix Suns wanted a definitive decision from the versatile forward in advance of the 2008 draft.
