"Everybody knows everybody's getting paid," Ball said Friday. "Might as well make it legal."
Ball said he did not receive money from agents during his one season at UCLA.
"My dad wasn't big on that," Ball said. "We just focused on going there and getting out."
Ball returned to the court Friday night for the first time since suffering a sprained left MCL in January. He missed 15 games.
He will not play in Saturday's game against the Sacramento Kings.
