For a second time, the Washington Bullets have denied permission to the New York Knicks to speak to Bullets General Manager Bob Ferry about a similar job in New York, according to Jerry Sachs, the top aide to Bullets owner Abe Pollin.

"As far as the Bullets are concerned, Bob Ferry is the best general manager in basketball and we want him to remain here and lead us on to another championship," Sachs said, reacting to a report in The Washington Post Friday that the Knicks still are interested in talking with Ferry.

"We would like to put the matter to rest with that statement," Sachs said.

He said that Richard Evans, president of Madison Square Garden Corp., who is conducting the Knicks' search for a coach and a general manager, called Pollin earlier this week and sought permission to interview Ferry. As he did four to six weeks ago, Pollin declined.

Neither Evans nor Pollin was available for comment.

Reached at his home yesterday, Ferry, who was noncommital Thursday about his interest in talking with the Knicks, said: "It's really great to be wanted. I've been happy here and I'm happy they're happy with me."

Ferry, a former Bullets player, has done the team's drafting since he was a scout in 1967.

He became general manager in 1973; only Jerry Colangelo of Phoenix, Ray Patterson of Houston and Red Auerbach of Boston have held an equivalent job longer among current executives.

The Bullets won the 1978 NBA title and reached the championship series the next season, losing to the Seattle SuperSonics, 4-1.

Since then, the Bullets have survived the first round of the playoffs only in 1982, when they beat the New Jersey Nets, 2-0, before losing to the Boston Celtics, 4-1.

Last season, the Bullets were swept by the Detroit Pistons, 3-0.

The Knicks have been without a general manager or coach since Scotty Stirling and Bob Hill, respectively, were fired at the end of the season.

Since then, many have been rumored to be seeking one of the jobs.

Jimmy Rodgers, the Boston Celtics assistant coach amd director of player personnel, interviewed for the Knicks coaching job on Thursday and reportedly is a leading candidate for that position.

The Celtics have said they expect compensation from the Knicks if they lose Rodgers, who has two years left on his contract.
