The Heat waived Chris Johnson and Reggie Williams after returning from Rio de Janeiro. The roster stands at 18 players, but teams can only carry 15 players during the regular season.
At this point, five players are competing for two roster spots: guards Shannon Brown, Tyler Johnson and Andre Dawkins, and forwards Khem Birch and Shawn Jones. Based on playing time and the Heat's needs, Brown and Dawkins appear to have inside tracks, but even those players aren't locks. The Heat also could waive all five players and sign two free agents to fill out its roster.
Dawkins is a young player with nice range, and that combination is tough to find on the Heat's roster. Brown offers a tough veteran presence and he told the Miami Herald last week that he's confident he'll be making the team.
