DALLAS -- NBA commissioner David Stern and Dallas Mavericks owner Mark Cuban, a pair of basketball power brokers who have differed on plenty of topics over the years, agree that they'd like to get rid of the one-and-done trend with draft prospects.

The rules currently require an American player to be at least 19 years old and a year out of high school before he can declare for the NBA draft, which is why the lottery is littered with phenoms coming off their college freshman seasons each year.

Stern said Tuesday that he'd like to add a year to the rule. Cuban wants to take it a step further, requiring players to wait three years after their high school class graduates to become draft-eligible.

"I just think there's every good reason to do it, which is obviously why we didn't do it," Cuban said sarcastically, adding that Kentucky fans were the only people who like the one-and-done concept.

It's a moot point unless the players' union agrees to change the draft-eligibility rules, something the NBA didn't make a priority while negotiating a new collective bargaining agreement during the lockout. At this point, the union has agreed only to form a committee to discuss changes.
