New Orleans already has a fairly crowded roster with 12 players on guaranteed contracts and six others with partially- or non-guaranteed deals.
Lawson spent most of the 2017/18 season in China playing for the Shandong Golden Stars. In 46 Chinese League contests, he averaged 25.5 PPG, 6.5 APG, and 2.2 SPG, shooting 40.1% on 3-point attempts.
He then signed with the Wizards on the last day of the regular season, making him eligible for the postseason. He appeared in five playoff games this spring, averaging 5.8 PPG and 3.0 APG in 19.2 MPG.
Wallace, 24, appeared in 30 games, including 19 starts, for the Clippers on a two-way contract last season. He averaged 9.7 PPG, 3.5 RPG and 2.4 APG in 28.4 MPG. He’s a restricted free agent, since the Clippers extended a qualifying offer to him in late June.
