A proposal that, in essence, would have awarded the draft rights to Virginia's Ralph Sampson to either the Dallas Mavericks or the Detroit Pistons by the National Basketball Association's board of governors.

If Sampson decides to quit school to become a professional, he must declare his intentions by April 25. But a coin toss to determine which team, Dallas or Detroit, will get him won't take place until April 30.

Dallas and Detroit finished last in the Western and Eastern conferences, respectively, this season. They will flip the coin to determine which gets to select first in the June 10 draft.

The 7-foot-4 Sampson, a sophomore who led the Cavaliers to the NCAA national semifinals this season, indicated two weeks ago he may consider skipping his last two years of college if he receives a good enough offer.

Both the Mavericks and the Pistons have been trying to lure Sampson out of school. But since neither could be sure of being first to draft, Detroit General Manager Jack McCloskey and Dallas General Manager Norm Sonju proposed that the coin flip be moved up to before April 25.

The matter was put before the board of governors, where 18 votes were needed for it to pass. Only 10 voted in favor, with nine against and four abstaining.
