Former LSU guard Javonte Smart, former Wisconsin center Micah Potter and ex-Missouri guard Dru Smith all signed Exhibit 10 contracts, which includes a training camp invitation. All three players were members of the Heat’s summer league team that competed in Sacramento and Las Vegas in July.
Another - former Kansas guard Marcus Garrett - signed a two-way deal, which will allow him to be available to play in 50 of the Heat’s 82 games this season. Another player - former Mississippi State guard D.J. Stewart - signed an Exhibit 10 deal with the Heat on Aug. 17.
Stewart, Smart, Potter and Smith likely will be given the chance to compete for a two-way contract, unless the Heat unexpectedly gives a two-way contract to a player signed to the 20th and final camp roster spot. The contracts also give the Heat the right to send all four of those players to their G-League affiliate in Sioux Falls, South Dakota.
Teams can sign as many as eight players to Exhibit 10 deals, allowing Miami to cycle through four more Exhibit 10 players - if it chooses - during training camp, provided Miami never exceeds 20 players in training camp at one time.
The Heat begins training camp Sept. 28 and opens the preseason Oct. 4 against Atlanta.
