Colin Castleton, Toronto Raptors
Summer League averages: 2.6 points, 4.0 rebounds, 1.8 turnovers, 11.4 minutes per game
Castleton is entering his third professional season and is currently an unrestricted free agent after a rocky 2024-25 campaign. The 6-foot-10 big man began the year on a two-way contract with the Grizzlies before being waived in January. He had brief stints with the Raptors and 76ers during the closing weeks of the regular season.
An elite rim protector without any shooting range, Castleton has struggled to find his place in the NBA. the 2025 Summer League certainly didn't help his cause, turning the ball over nine times and shooting just 33 percent from the field in five games played.
Zyon Pullin, Memphis Grizzlies
Summer League averages: 7.3 points, 2.3 rebounds, 5.3 assists, 3.0 turnovers, 20.3 minutes per game
Pullin was waived Sunday from his two-year, two-way contract he inked with the Grizzlies in January, opening up a slot for Memphis to sign Clemson alum P.J. Hall. Pullin appeared in just three games with the Grizzlies as a rookie. He had previously been signed to the Heat after going undrafted in the 2024 NBA Draft.
The 24-year-old will now hit the open market. He averaged 20.9 points, 6.4 assists, 5.2 rebounds and 1.5 steals per game in the G League last season.
Keyontae Johnson, Denver Nuggets
Summer League averages: 2.3 points, 2.0 rebounds, 1.0 assists, 11.3 minutes per game
Johnson may have finished his collegiate career with Kansas State, but his four years in Gainesville will not go forgotten. The No. 50 overall pick in the 2023 NBA Draft, Johnson appeared in nine games as a rookie with Oklahoma City and spent the entire 2024-25 campaign in the G League with the Greensboro Swarm -- an affiliate of of the Charlotte Hornets. Johnson averaged 17.7 points, 4.7 rebounds and 2.7 assists per game in the G League.
Trying to find a new home for the 2025-26 campaign, Johnson struggled to make an impact in Summer League. Unless a suitor comes out of the woodwork, expect Johnson to remain at the G League level.
