The Heat have to trim to an NBA maximum of 15 by the start of the regular season. Two players on the camp roster, however, can be exempted from the 15-player limit by signing two-way contracts. Undrafted Michigan guard Derrick Walton Jr. has already agreed to one such deal, with undrafted Central Florida guard Matt Williams Jr. possibly to be converted to a second such contract. Such contracts limit a player to 45 days on an NBA roster, the rest of the season to be spent in the G League.
