When Boston announced its Summer League roster on July 8, Hugo Gonzalez was returning with a distinction already on his record: he had become the third Celtic to start an NBA game before turning 20.
The announcement identified Gonzalez and Amari Williams as returning players headlining the roster. Assistant coach Amile Jefferson was assigned head-coaching duties for the Las Vegas group.
Gonzalez's previous Summer League, in 2025, produced averages of 10.8 points, 4.5 rebounds and 2.8 assists over four games. Those are last summer's numbers, not a report of his 2026 results.
For a young NBA wing, the value of a second summer is the chance to compare decisions as well as production. How quickly does he move the ball? Can he keep a possession organized under pressure? Those questions provide a better viewing checklist than treating a short summer sample as a season prediction.

His own view of the adjustment
In a July 4 interview with AS, Gonzalez said he had spent about three weeks on vacation and three weeks training in Boston, moving between the United States and Madrid. He described gaining experience from living abroad.
That interview adds a personal account of the transition behind the statistics.
How the second summer finished
The team's July 20 wrap-up supplies the results missing from the initial roster announcement. Gonzalez led Boston in Summer League scoring at 18.3 points per game and assists at 5.7. He ranked second on the team in rebounds, with eight per game, and steals, with 1.7.
Boston finished 3-2. Gonzalez did not play in the finale against Orlando; Cenac and Mitchell were also held out. That distinction matters when comparing individual averages with the team's five-game record.
The results show a broader contribution than scoring alone. Rebounding and assists belong beside his points when reviewing the July assignment. They also give the opening viewing questions an actual sample to work from, rather than leaving the story at the announcement of his participation. The attached Boston-produced season highlights cover a different period. Keep those NBA clips and these Summer League totals separate when assessing what changed between his first and second summers.
