A: For the moment, most likely no one. This is a time when the Heat could use a year's head start on the two-way D-League contracts that will come into play next season. That would allow, amid all these injuries, the opportunities to get sneak previews at the possibilities of Okaro White or Briante Weber. But until the Feb. 23 trading deadline it remains more prudent for the Heat to hold on to even the expiring contracts on the roster, if only to have salaries available to use in trades. There have been times in previous seasons when the Heat have been able to make deals work by amounts far lower that even the minimum salary. So while Derrick Williams and Luke Babbitt may hold less for the future than prospects such as White and Weber, what they hold now is potentially valuable cap space.
