NEW YORK (AP) -- David Stern would love a system in which Anthony Davis and the rest of Kentucky's freshmen stars were required to try to repeat.
Instead, the NBA commissioner could end up calling Davis' name in June as the first pick in the draft.
The league wasn't able to change its draft eligibility rules during collective bargaining last year. The rules require an American player to be 19 years old and a year out of high school.
"We would love to add a year, but that's not something that the players' association has been willing to agree to," Stern said Tuesday.
The union would only agree to form a committee to discuss changes, and Stern knows the players are unlikely to consent to an increase without some concession from owners.
