Michael Graham probably will not be allowed to play for Georgetown next season because of NCAA academic eligibility rules, but he showed in the Kenner summer basketball league championship game yesterday what his presence could mean in a Hoya front court with Patrick Ewing, Bill Martin and freshman Reggie Williams.

He finished with a team-high 19 points and played a key role by filling in for a foul-troubled Ewing to help 1789 to a 107-102 victory over Nike in the championship game before 2,500 at McDonough Arena.

In an otherwise uneventful first half, when 1789 took a 15-point lead, Graham made five impressive and effortless slam dunks. He had 14 points in the half.

Even without Ewing, who scored eight points and blocked three shots before being benched with three fouls, the 1789 front line dominated play at both ends of the court and led, 55-40, at the intermission.

The lead remained in double figures most of the second half.

Ewing fouled out with 6:18 to play, and his team leading, 89-74.

Nike began a furious comeback behind Martin, the only Hoya in its lineup, running off a 26-6 spurt that made it 95-90 with 2:20 remaining.

Martin scored eight points in that spurt and Howard University's Ed Swails had six.

At that point, Williams and teammate Phil Morgan of UDC combined to finally stop the Nike rally. Morgan made two free throws for a 97-90 lead.

Swails hit a jump shot, but six points by 1789 virtually clinched the game.

Morgan made two more free throws and, after a missed shot, Williams finished a three-on-one fast break with a commanding slam dunk and a 101-92 lead.

Williams and Jay Nichols of Delaware Valley finished with 18 points each, Morgan had 16 and Ewing 17. Martin led all scorers with 26 points and eight rebounds.
