Hart finished the 2006-07 season with the Clippers, nearly helping lead the team to the playoffs. He signed with the Jazz as a free agent last summer but lost his job to Ronnie Price 50 games into the season and finished the year out of the rotation.
The Clippers signed Knight last summer after they were unable to sign free agent Steve Francis. Knight, who turns 33 in November, averaged 4.6 points and 4.4 assists in 74 games last season, starting 39.
Knight signed a two-year, $3.2 million contract with the Clippers and will make $1.6 million this season. Hart signed a two-year, $4.8 million contract with the Jazz and will make $2.484 million this season.
The Jazz signed Hart hoping he could help fill the void after Derek Fisher asked to be released from his contract. But Hart struggled with the limited minutes available backing up Deron Williams and shot a career-worst 32.2 percent.
Hart grew up in Los Angeles and questioned his decision not to re-sign with the Clippers as he struggled during his first season in Utah. Hart exercised an option to return to the Jazz but he did look at signing with Denver and the Clippers as buyout possibilities.
