David Stern would prefer that players be at least two years removed from high school before they can declare for the NBA draft.

“I think it would be a great idea to change it to two-and-done," Stern said. "Everyone I hear from -- NBA players, actually; college coaches; NBA teams -- everyone says it's a pretty good idea, except the [NBPA], whose consent is necessary to change it. So, what I tell people to do is, 'Don't call me, call their union.'"

Stern is opposed to reverting back to the old rule, which allowed players to enter the draft directly out of high school.

"We have the current rule, which is one year form high school ... because it's good for our business," Stern said. "We didn't do it to help or hurt the colleges. Any college could decide not to take a player who was likely to leave after a year, but indeed it would probably cost the college president his job."
