Ja’Kobi Gillespie entered the NBA with a reputation as a skilled playmaker and reliable scorer, but the San Antonio Spurs rookie admits the transition to the professional level has already presented new challenges. Selected with the 42nd overall pick in the 2026 NBA Draft, Gillespie is using the Summer League as an opportunity to adapt while proving he belongs on an NBA roster.

The former Tennessee standout made his Summer League debut in a narrow 88-87 loss to the Miami Heat. Although his shooting performance left room for improvement, the rookie displayed several encouraging qualities by contributing across multiple areas of the game and showing the composure expected of a point guard.

Like many first-year players, Gillespie is adjusting to a faster pace, stronger opponents, and greater physical demands than he experienced during his successful collegiate career. The early stages of Summer League are designed for exactly that purpose, allowing prospects to gain valuable experience before training camp begins.

With San Antonio continuing to build its young core, every Summer League appearance offers an important chance for the organization’s newest players to develop. Gillespie understands the learning process has only just begun, but both he and the coaching staff believe there are already positive signs to build upon.

1. Adjusting to the NBA Game

Gillespie acknowledged that one of the biggest differences between college basketball and the NBA is the overall athleticism of the competition. Facing larger, quicker, and more explosive players every night has required him to make immediate adjustments to both his offensive and defensive approach.

Standing 6-foot-1, Gillespie joked that he has often been one of the smallest players throughout his basketball career. However, he noted that despite the increased size of NBA opponents, he no longer feels dramatically undersized once games begin, even though the physicality remains a significant adjustment.

His first Summer League performance reflected both the challenges and the promise of that transition. Gillespie finished with 10 points but struggled with efficiency, making just three of his 17 field-goal attempts. Despite the difficult shooting night, he contributed eight assists and four rebounds while consistently helping organize San Antonio’s offense.

Those additional contributions highlighted the value Gillespie can provide even when his shot is not falling. His willingness to create opportunities for teammates and maintain control of the offense demonstrated the well-rounded skill set that attracted the Spurs during the draft.

2. Coaches See Encouraging Progress

Spurs Summer League head coach Corliss Williamson focused less on Gillespie’s shooting numbers and more on the rookie’s overall impact. He praised the young guard for maintaining composure, directing the offense, and helping teammates find quality scoring opportunities throughout the game.

Williamson noted that Gillespie handled ball-handling responsibilities effectively while getting the team organized during important stretches. He also highlighted the guard’s ability to penetrate into the lane, collapse the defense, and generate open looks for others despite facing the speed and athleticism of NBA-level competition.

The coach emphasized that player development is the primary objective during Summer League rather than immediate statistical success. Young players are expected to make mistakes while learning new systems and adjusting to a higher level of competition, making steady improvement more important than individual box-score numbers.

Williamson also expressed confidence that Gillespie will continue growing as he gains experience. The coaching staff believes his decision-making, leadership qualities, and willingness to learn provide a solid foundation for continued progress throughout the offseason.

3. Opportunity Awaits in San Antonio

Gillespie arrives in the NBA following an accomplished college career that included stops at Belmont, Maryland, and Tennessee. Across 130 collegiate games, he developed into one of the nation’s most productive guards, averaging 15 points, 4.5 assists, and nearly two steals per game while shooting efficiently from the field.

His senior season at Tennessee represented the high point of his college career. Gillespie averaged 18.4 points and 5.4 assists while earning SEC Newcomer of the Year honors, First Team All-SEC recognition, and selection to the NCAA Midwest Region All-Tournament Team after helping lead the Volunteers through a successful campaign.

Before arriving in Knoxville, Gillespie enjoyed productive seasons at both Maryland and Belmont. At Maryland, he played a key role in helping the Terrapins reach their first Sweet 16 in nearly a decade, while his earlier years at Belmont earned him conference recognition for both his defensive play and overall development.

San Antonio’s rebuilding roster presents valuable opportunities for young players to earn meaningful roles, particularly with first-round pick Jayden Quaintance currently sidelined as he recovers from knee surgery. As the Summer League continues, Gillespie will have additional chances to showcase his playmaking ability, improve his scoring efficiency, and strengthen his case for a consistent role entering his rookie NBA season.
