NBPA executive director Michele Roberts made her position on raising the age limit to 20 clear on Friday when she said: "Be happy with one-and-done; it's not going to be two-and-done."

Adam Silver has long advocated for an age limit of 20.

"I think it would be much better for the game if the minimum age was 20 instead of 19," he said. "I understand the other side of the issue. We haven't had the opportunity to present our side of the issue."
