San Antonio Spurs center-in-waiting David Robinson will have to decide whether to petition the new Navy secretary for an early release of his two-year commitment because the NBA team won't, said club chairman Angelo Drossos.

Robinson, the Naval Academy all-America who signed an eight-year, $24 million Spurs contract in November, is attending classes at the Navy's Civil Engineering Corps school in Port Hueneme, Calif.

Navy Secretary James Webb, who resigned Monday, had ruled Robinson could not play in the NBA until 1989-90. Now, Bob Bass, Spurs executive, agreed with Drossos, "It will all be up to David Robinson and his people," to see if anything can be worked out with, presumably, secretary-designate William L. Ball III.

Robinson could not be reached immediately, but Carl Liebert, his academy roommate/teammate, said the developments might change Robinson's mind about trying to go from the '88 Olympics to the pros: "He's happy with what he's doing, but, God, it's killing him not to be playing ball." . . .

Guard Jim Paxson is a Boston Celtic and ex-Bullet Darren Daye isn't. The Portland Trail Blazers dealt Paxson, their all-time leading scorer, for reserve guard Jerry Sichting and future considerations, mainly to shed Paxson's contract worth $850,000 this season, $1 million next. Sichting has been on the injured list after knee repair, so to make room for Paxson the Celtics waived Daye.
