Brook Lopez played in three arenas, for nine coaches and with numerous teammates.
He also survived numerous trade rumors.
Russell was the second pick of the Lakers two years ago out of Ohio State. He averaged 13.2 points as a rookie and improved to 15.6 points last season as the Lakers won 26 games.
"We are extremely excited to welcome D'Angelo and Timofey to our Brooklyn Nets family," Nets general manager Sean Marks said in a statement released by the team. "D'Angelo is a versatile young guard with a bright future and we are enthusiastic about continuing his development along with our young nucleus, while Timofey will provide a veteran presence who can contribute on both ends of the floor. Both are great fits within Kenny's system."
Also going to the Lakers are the rights to forward Kyle Kuzma, who was drafted with the 27th pick.
The Nets drafted Lopez with the 10th overall pick in 2008 when the team still played in the Meadowlands in East Rutherford, N.J. He played two seasons in Newark before the team moved to Brooklyn in 2012.
"We would also like to thank Brook for all of his contributions to the team over his nine seasons with the Nets," Marks said. "As the franchise's all-time leading scorer and longest-tenured player, he has been an exemplary member of the organization and always represented the Nets with class both on the court and in the community. We wish Brook and his family nothing but success in the future."
Lopez appeared in 562 games with the Nets and averaged 18.6 points, 7.1 rebounds, 1.5 assists in 32.2 minutes. Last season, he averaged 20.5 points and expanded his game to include 3-point shooting while becoming the longest tenured-player in franchise history.
"To Brook Lopez, a huge personal thank you for your integrity and commitment to the team over the last nine years," Nets owner Mikhail Prokhorov said in a statement.
Lopez also surpassed Buck Williams as the franchise scoring leader with 10,444 points, and he is the Nets' career leader in blocked shots with 972.
In 423 games with the Knicks, Denver, Cleveland and the Lakers, Mozgov has averages of seven points and five rebounds. In the first season of four-year, $64 million contract, the 30-year-old averaged 7.4 points and 4.9 rebounds in 54 games.
Kuzma averaged 10.1 points in 96 games during three seasons with Utah. Last season, he led the Utes in scoring (16.4 points) and rebounding (9.3).
