In a shortsighted dash for immediate roster tweaks during the 2023 NBA Draft, the Boston Celtics made what could go down as one of their most regrettable decisions: trading away the rights to the No. 39 pick, which became the promising Mouhamed Gueye, to the Atlanta Hawks in exchange for a distant 2027 second-round pick. At the time, it might have seemed like a minor footnote in their championship pursuit, but fast-forward to this season, and it’s crystal clear—this was a colossal blunder. Gueye, the athletic 6-foot-11 powerhouse who’s now thriving in Atlanta, could have been the ultimate “glue guy” seamlessly slotting into Boston’s revamped defensive system. Instead, the Celtics are left watching from afar as league contenders salivate over his potential, wondering what might have been.
Up to now, Gueye has tantalized with glimpses of his raw talent, but this year, he’s finally hitting his stride, emerging as a reliable rotation piece for the Hawks. Not only is he logging consistent minutes, but his skill set screams “perfect Celtics fit” in Joe Mazzulla’s high-energy, defense-first scheme. Imagine pairing him with Boston’s young defensive dynamos like Jordan Walsh, Josh Minott, Baylor Scheierman, and Hugo Gonzalez—the group that’s been spearheading the Celtics’ suffocating defensive charge. Gueye’s elite athleticism, relentless hustle, and instinctive playmaking would have elevated that unit to another level, making him an ideal complement rather than the one that got away.
Back in 2023, Boston could have snagged both Walsh at No. 38 and Gueye at No. 39, building a formidable tandem of versatile forwards. But by shipping Gueye off for that future second-rounder—a classic “win-now” maneuver that prioritized short-term flexibility over long-term upside—they handed Atlanta a gem. And boy, is he shining there. While his box-score stats might not scream superstar—5.8 points, 3.8 rebounds, and 1.0 assists per game on 49.6% field-goal shooting and 26.9% from three on 2.1 attempts—Gueye’s impact transcends the numbers. He’s appeared in all 25 of Atlanta’s games this season, averaging 17.2 minutes while splitting time between power forward and center.

What really sets Gueye apart is his defensive prowess. His shot-blocking instincts and ability to disrupt plays have been nothing short of electric, even if fouling remains an occasional Achilles’ heel. Sound familiar? It’s eerily similar to the raw edges Mazzulla has polished out of Walsh, Scheierman, and Minott, transforming them into key contributors who are fueling Boston’s wins. At 6-foot-11, Gueye would have been the tallest in that crew, offering tantalizing versatility as a small-ball center—much like Minott’s role—in Mazzulla’s innovative lineups. His hustle and length could have fortified the Celtics’ frontcourt depth, providing that extra layer of athleticism to dominate on both ends.
Sure, the Celtics aren’t exactly hurting. They’re stocked with solid young role players and remain a powerhouse in the East. But let’s not sugarcoat it: keeping Gueye would have supercharged their development pipeline, turning an already strong roster into an unstoppable force. Who knows how the 23-year-old would have evolved under Mazzulla’s guidance? Instead, he’s blossoming in Atlanta, drawing envious glances from contenders across the league who see him as the kind of versatile, high-upside big man that could swing a playoff series.
This trade isn’t just a missed opportunity—it’s a franchise misstep that stings more with every Gueye highlight. As Boston chases another banner, they’re left pondering the “what ifs,” while rivals lick their lips at the thought of poaching a player who could have been the missing piece in green. Hindsight is 20/20, but this one? It might haunt the Celtics for years to come.
