Robinson, 29, is 6-foot-6 and last played in the NBA during the 2020-21 season, when he appeared in 23 games with the Kings. He has also spent time with the 76ers, Pacers, Pistons, Warriors and Timberwolves.
He was waived by the Kings in February 2021.
Stevens, 26, is 6-6 and spent each of his first three seasons with the Cavaliers, before being traded to the Spurs this summer. The Spurs waived him shortly after the trade.
A hustling, physical player, Stevens appeared in 62 games last season, averaging 5.3 points and 3.3 rebounds. He also served as a reliable perimeter defender and a guy who made plays that don’t show up on the stat sheet.
Originally undrafted out of Penn State, he had his two-way contract converted to a standard deal in April 2021.
Warren, 29, is 6-8 and undoubtedly the biggest name of the bunch, mostly because of his play in the NBA Bubble in 2020 while with the Pacers, when he averaged a career-high 19.8 points.
He suffered knee and foot injuries after that, though, appearing in just four games the following season and missing all of 2021-22.
In 42 games with the Nets and Suns last season, Warren averaged 7.5 points on 45 percent shooting and 80 percent from the free-throw line.
King, 23, is 6-7 and appeared in one game last season with the 76ers. He has also spent time with the Kings and Pistons since entering the NBA in 2019, with career averages of 4.8 points and 1.6 rebounds.
