Jones, a 6-foot-10 center-forward, who grew up in Eustis and attended South Florida, is a seven-year NBA veteran.
Eric, a 6-11 center, played in just one game last season with the Cleveland Cavaliers.
Harris, a 6-5 guard, played for BC Azovmash of the Ukraine League last season after appearing in a total of 76 games the previous two seasons with the Cavaliers.
