The Miami Heat returns to the court for the start of training camp Tuesday. This week’s position-by-position breakdowns help preview the beginning of camp. The focus of the third part of the series is small forward. Josh Richardson is expected to begin the season as the starter at this position for the second consecutive year, with Justise Winslow, Rodney McGruder and Derrick Jones Jr. as his backups. Duncan Robinson, who is signed to a two-way contract, can have his two-way deal switched to a standard contract if he really impresses in the preseason. But it’s more likely that Robinson ends up as part of the organization’s G League affiliate in Sioux Falls, South Dakota, to start the year.
