Eddie House had virtually disappeared from the Boston rotation during the Celtics' run to the NBA title. When he got in the game, though, he showed his worth.

House, who made a key 3-pointer while pouring in 11 points in 25 minutes in Game 4 against the Los Angeles Lakers, agreed to terms with the defending champions on Monday. Tony Allen, another backup guard whose development slowed when he tore ligaments in his knee during the 2006-07 season, also re-upped with the team.

The Celtics lost sixth man James Posey to free agency last week, but Monday's deals give the team a chance to return most of its key players when it goes for an 18th title next season. All five starters are under contract, and only injured Scot Pollard and aging veterans P.J. Brown and Sam Cassell are left on the market.

NETS ACQUIRE DOOLING: The New Jersey Nets acquired guard Keyon Dooling from the Orlando Magic in a sign-and-trade deal on Monday. In exchange for Dooling, the Nets gave the Magic cash and the trade exception they got in the deal that sent Jason Kidd to the Dallas Mavericks.

REFEREE RESTRUCTURING: The NBA appointed Bernie Fryer and Joe Borgia to new positions and reassigned Ronnie Nunn on Monday in a series of moves to restructure its referees program. The league also recently hired Gen. Ron Johnson as its senior vice president of referee operations as it tries to strengthen its officiating operations following the Tim Donaghy scandal. Fryer, who officiated nearly 1,700 games in his 28-year career, was promoted to vice president and director of officials. He will oversee the daily management and performance on the court of the referees. Borgia becomes vice president of referee operations, responsible for areas such as the recruitment and training programs. Nunn will now report to Fryer as director of development.
