The Heat trimmed its roster to the maximum-permitted 15 by releasing forward Eric Griffin and center Justin Hamilton on Saturday.
Of the players who remain, only two have nonguaranteed contracts: forward Michael Beasley and guard Roger Mason Jr. Their deals would not become fully guaranteed until Jan. 10.
Beasley said last week he felt “nervous and anxious” about his predicament.
But Heat coaches and teammates have been impressed with his growth.
“He’s more mature,” forward Udonis Haslem said. “He understands this is a privilege. He’s coachable, and he listens.”
Beasley said his defense also has improved.
As for Mason, “his skill-set fits what we do,” Heat coach Erik Spoelstra said earlier this month. “We tried to get him on our team five years ago. He’s unique with his size, his ability to play two positions. When you put him in a system, because of experience it looks like he’s played in our system a long time.”
Griffin, an undrafted player from Campbell who flashed considerable athleticism in preseason games and practices, said Friday he is considering playing in China.
Hamilton, the Heat’s second-round pick out of LSU in 2012, said he would consider an offer from the NBA’s Development League. The Heat is looking to stock its NBDL affiliate in Sioux Falls, S.D.
Teams have until 5 p.m. Monday to reduce their rosters to no more than 15 players and are required to keep at least 13.
The Heat opens the regular season at home Tuesday night against Chicago.
