NBA Summer League disappointments: Darryn Peterson, Keaton Wagler, the Thunder and more

Key Points:

• Chicago Bulls' Dailyn Swain struggled significantly in NBA Summer League, shooting 4-for-31 overall and finishing with a -0.27 PER, the lowest among qualifying players, but his poor performance may not predict his regular-season success.
• Darryn Peterson, the Utah Jazz's second overall pick, showed scoring ability with four 20-point games but struggled as a lead guard, posting nearly as many turnovers as assists and facing challenges against interior defense.
• Several Oklahoma City Thunder rookies, including lottery pick Aday Mara and point guard Bennett Stirtz, had disappointing Summer League performances, contributing to one of the worst team showings in history with eight straight losses.
• Other notable underperformers included Knicks' Mo Diawara, Bulls' Noa Essengue, Clippers' Keaton Wagler, Kings' Darius Acuff and Alex Karaban, and multiple Brooklyn Nets rookies, highlighting concerns about their readiness and potential impact.
• Despite the overall disappointing Summer League for many prospects, analysts caution against overreacting, noting that Summer League performances are not definitive predictors of future NBA success and encourage optimism for player development.
