A flurry of movement prompted yesterday by the raising of the NBA salary cap resulted in the relocations of former Washington Bullet Manute Bol, veterans Paul Pressey and Danny Ainge, and ex-Michigan star Terry Mills, the latter even before playing a professional game.

Bullets General Manager John Nash said his team "had a good deal of conversation with some interesting opportunities, but we're not close to anything right now." Nash, in a telephone interview from Los Angeles where he is scouting Southern California Pro Summer League games, added that "the cap enabled some teams to make trades they have wanted to do for awhile." While there "are some other trades pending," Nash stressed the Bullets are not involved at this stage.

The league increased its salary cap more than $2 million, from last season's $9.8 million to $11,871,000 in 1990-91. The minimum amount teams are required to spend on players' salaries was raised proportionally, from nearly $8 million to $9.6 million. That will push the average salary of an NBA player to $916,000 from last year's $750,000.

A collective bargaining agreement signed in April 1988 requires the league to raise the salary cap on Aug. 1 of each year, according to a formula in the contract. The yearly salary cap multiplied by the number of NBA franchises must equal 53 percent of the league's revenue.

"The NBA has been on an upward spiral in recent years, so the cap has jumped," NBA spokesman Terry Lyons said. "It's increased at a faster rate the last two seasons because of the league's success."

He said the four expansion franchises awarded recently have not had a significant effect on the higher rate of increase, although they remain among the league's most successful teams in terms of revenue.

"What accounts for this year's increase is the new television contract," Lyons said. The league recently signed agreements with NBC and TNT totaling $875 million over four years.

Movement among several teams began almost immediately once the new salary cap took effect. The Golden State Warriors dealt 7-foot-7 Bol, a five-year veteran who spent the first two years with the Bullets, to the Philadelphia 76ers for a 1991 first-round draft choice. Bol, 27, played in 75 games last season with the Warriors, finishing with 238 blocked shots (3.17 per game), fourth-best in the league. Bol, the NBA shot-blocking leader two of his five seasons, likely will back up Mike Gminski at center.

Mills became a Denver Nugget before ever suiting up in Milwaukee. The Bucks swapped 6-10 Mills, drafted 16th overall, for veteran center Danny Schayes, then later in the afternoon traded 1982 first-round pick Pressey, 6-5, to the San Antonio Spurs for 6-10 Frank Brickowski.

Schayes and Brickowski are expected to shore up the Bucks' front court, depleted when it was learned forward Larry Krystkowiak has not sufficiently recovered from a severe knee injury suffered in the 1989 playoffs. Krystkowiak, who played in 18 games last season, may require reconstructive surgery.

Milwaukee also announced it had relinquished the rights to veterans Ben Coleman, a former Maryland player, and Tony Brown because of the salary cap.

The Sacramento Kings traded Ainge to the Portland Trail Blazers for guard Byron Irvin, a 1991 first-round pick, and second-rounder in 1992. Ainge, returning to the state where he starred in high school, played on championship teams in Boston in 1984 and 1986. He is slated to back up Clyde Drexler and Terry Porter in the Portland back court.

Meanwhile, Yugoslavian Dino Radja reportedly will forego joining the Celtics to sign with Italy's Il Messaggero. Boston, which drafted Radja in 1988, had signed the 6-11 forward to a multiyear contract beginning in 1990-91, but will lose him to the team that signed Danny Ferry and Brian Shaw last season, according to the Boston Globe.

However, a Messagerro spokesman said that "if there were {such an agreement}, Messaggero would be the first to announce it."
