This leaves us with Horford, Crowder, Smart, Hayward, Brown, and Zizic as the only people who can play forward or center. It leaves us with a point guard, 3 small forwards, a power forward, and a rookie center to man the 3,4, and 5 spots for 48 minutes/game. It also leaves us with no ability to handle an injury to Horford or Zizic whatsoever.
If we are lucky enough to get Hayward and Fultz, I expect some guards leaving to bring in proven bigs or keep a few current ones and get some other compensation like draft picks.
