​LAS VEGAS – Summer League is designed to answer questions, not define careers.For the Phoenix Suns, four games proved to be enough to give them the answers they needed surrounding three of their young stars.Feb 22, 2026; Phoenix, Arizona, USA; Phoenix Suns center Maluach (10) and forward Rasheer Fleming (20) against the Portland Trail Blazers at Mortgage Matchup Center.

Rebilas-Imagn ImagesAdvertisementAdvertisementAdvertisementBy shutting down rookies Khaman Maluach, Rasheer Fleming, and Koa Peat for the remainder of Summer League, the organization made a decision that speaks louder than any box score. Phoenix isn’t interested in collecting another exhibition victory. Instead, it’s protecting three players it believes can become meaningful contributors for years to come. Organizations often walk a fine line during Summer League. Young players need live repetitions, but every additional game also carries injury risk before training camp even begins. Once coaches feel they’ve gathered enough film, evaluated decision-making and confirmed a player’s competitive instincts, the value of another appearance begins to diminish.Dec 23, 2025; Phoenix, Arizona, USA; Phoenix Suns center Maluach (10) against the Los Angeles Lakers at Mortgage Matchup Center.

Maluach showcased why the franchise believes he can anchor the interior with his length, mobility and defensive instincts. Fleming flashed the versatility that modern NBA teams covet, demonstrating an ability to impact both ends of the floor while fitting multiple lineup combinations. Peat, meanwhile, continued to validate his reputation as one of the organization’s most intriguing and explosive long-term pieces, showing poise that exceeded typical rookie expectations. Perhaps the biggest takeaway isn’t individual statistics; it’s organizational confidence.Peat (left) with Suns GM Brian Gregory during an introductory press conference at the Verizon 5G Performance Center, in Phoenix, on June 26, 2026. © Mark Henle/The Republic / USA TODAY NETWORK via Imagn ImagesAdvertisementAdvertisementAdvertisementThe Suns now have the opportunity to transition all three prospects into the next phase of development. That means learning alongside established veterans, absorbing NBA systems during training camp and earning meaningful preseason opportunities instead of risking unnecessary setbacks in July. Strong NBA organizations know development is a marathon, not a sprint. Phoenix’s decision suggests the franchise has already seen what it needed to see. Protecting the health of three promising young players today could pay dividends throughout the season and, more importantly, for years to come. Sometimes the smartest development move isn’t giving prospects another game; it’s knowing exactly when they’ve already proven enough.Two reasons Diamondbacks fans must watch tonight’s MLB
