The Heat are working out free agent guard Roger Mason Jr., who is now the vice president of the player's union. He appeared in 69 games for the Hornets last year, averaging 5.3 points on .433 shooting, along with 66 3-pointers on the season. The Heat have 13 players under contract, meaning Mason has a chance to make the team's final roster. And if he does, he'll be nothing more than a 3-point specialist, as usual.
