The Knicks and Raptors have agreed in principle on a revised trade that will bring 7-foot shooter Andrea Bargnani to New York.

Free agent Quentin Richardson has been added to the deal and will be sent to Toronto in a sign-and-trade, along with Marcus Camby, Steve Novak, a 2016 first-round pick and second-rounders in 2014 and 2017, league sources said. The deal won't be official until the NBA moratorium is lifted July 10.

The original trade that the two sides agreed upon Sunday did not include Richardson, but because the NBA didn't approve it by midnight, it had to be reworked.

Players' salaries changed Monday, the start of the free-agent negotiation period. Bargnani's salary increased, Camby's and Novak's decreased, and Richardson had to be included to make the salaries match up. Richardson, whom the Knicks signed April 16 to fill a roster spot, will get the veteran's minimum in 2013-14.

The trade leaves the Knicks with six players under contract. Their priorities are to re-sign J.R. Smith, Pablo Prigioni and Chris Copeland, and they'd like to bring back Kenyon Martin.

Coach Mike Woodson and other team officials met with Smith Monday shortly after midnight, a league source said. All signs point to his return.

The Knicks can give Smith a multiyear deal starting at roughly $5.6 million. Other teams could offer more and a chance to start. But he is from New Jersey, likes playing close to home and has been given more of a green light under Woodson.

"I don't want to predict free agency because it's been crazy the last couple of years, so I don't know exactly what's going to happen," Knicks general manager Glen Grunwald said. "But we're going to do what we can to get J.R. back."

The Knicks also plan to do what they can to keep Prigioni, a restricted free agent. He had a strong rookie season and they need help at point guard.

Keeping Copeland, who also is restricted, might be more difficult because the most the Knicks can give him is the $3.18-million mini-midlevel exception. But they may want to split that on multiple players or use it to sign a proven veteran.

Copeland's agent, John Spencer, said he has received interest from the Pacers, Jazz, Lakers, Mavericks and Pelicans. He called the Pacers' interest "intriguing" and said Copeland could meet with some teams later in the week. "He's going to listen to everybody," Spencer said. "He would always want to go back to New York, but we're going to talk to everybody."

The Knicks also have contacted or will reach out to free agents such as Aaron Brooks, Will Bynum, Tony Allen, Carlos Delfino, Matt Barnes and Dahntay Jones.

Bargnani, the No. 1 overall pick in 2006, has career averages of 15.2 points and 4.8 rebounds. The Knicks could play him at power forward and center. He's not a good defender or rebounder, but he can spread the floor with his shooting and could create matchup problems, especially if he's on the floor with Carmelo Anthony. Bargnani, 27, could force centers to come out and guard him, which would open the interior.

A change of scenery might be what the inconsistent Bargnani needs. He was booed often in Toronto last season. Hampered by right wrist and elbow injuries, he shot 39.9 percent and averaged 12.7 points in 35 games.
