McRoberts, an outside-shooting power forward who is a deft playmaker, was not available for comment during Tuesday's media-availability session. He is among the candidates to start at power forward in place of Chris Bosh, who failed his Heat physical last week and no longer is in the Heat plans, according to Heat President Pat Riley. McRoberts, who started 78 games in Charlotte the season prior to his arrival in South Florida, has started just five for the Heat in his two seasons, only one in 2015-16.
