Michael Graham, the 6-foot-9 forward who helped Georgetown win the 1984 NCAA basketball title, has signed with the Albany Patroons of the Continental Basketball Association.

He had left GU because of what Coach John Thompson called "inconsistencies in his approach to academics," then was ruled ineligible at the University of the District of Columbia because he didn't take enough classes.

"Nobody has ever drafted him, he was available and we signed him," General Manager Gary Holle of the Patroons said, noting Graham will get "between $5,500 and $6,000" for the 48-game season. The Patroons will open training Wednesday under ex-Knick Phil Jackson . . .

The Los Angeles Clippers have 15 days to match the offer sheet the Seattle Supersonics gave free agent guard Norm Nixon. He earned $413,000 with the Clippers last year . . .

The Milwaukee Bucks extended Coach Don Nelson's contract through spring 1990. His Milwaukee teams are 441-291 . . .

John Kuester, the new basketball coach at George Washington University, will make his debut at 7:30 p.m. Sunday when the Brisbane Bullets, an Australian team, plays at the Smith Center . . .

It will cost adults $2 and children $1 to see Navy's basketball team scrimmage at 4 p.m. Sunday and Maryland's at 5 p.m. at Navy's Halsey Field House; it had been announced there would be no charge . . .

Denise Barbour's two foul shots with 12 seconds left in overtime gave the Georgetown women a three-point lead that enabled them to beat the Irish Olympic Team, 59-58, before 515 at McDonough Arena.

Carol Buckley of Ireland had tied it, 53-53, by scoring with 25 seconds left in regulation. Ann Gothard's 18 points and nine rebounds led GU in its first game this season, although it does not count in the standings. The visitors are 0-3 halfway through their U.S. tour.
