Ja’Kobi Gillespie Is the System

Standing 6’1 and listed 188 pounds (per Tennessee athletics website), senior guard Ja’Kobi Gillespie was one of the most sought-after transfers in the country, ranked as the 12th overall portal commit by 247 Sports. Despite Gillespie’s plaudits and his background as a Tennessee native, growing up only an hour away from Knoxville, his addition has flown under the radar.

The lack of fanfare is somewhat understandable, considering Gillespie’s nomadic college career so far, along with Tennessee welcoming a projected top-5 pick in Nate Ament to campus this season. However, playing in the shadow of a blue-chip recruit is a position Gillespie is well familiar with, after playing with 2025 lottery pick Derik Queen this past season. Similar to the 2024-25 season, I expect Gillespie to not only perform at the same level as his highly regarded counterpart but also to exceed Ament’s production at times, just as he did with Queen.

My confidence in Gillespie is based on his track record of steady and significant improvement, which has placed him on a developmental trajectory that has elevated him to becoming a bona fide NBA prospect and a player well worth first-round consideration come draft time in 2026. And with college basketball currently in a state of perpetual flux, it has never been more important to account for the various contextual factors, from scheme to personnel, which when ignored could obfuscate a prospect’s professional potential.

Making the Leap

What I found initially striking within Gillespie’s prospect profile was the dramatic leap he made from his sophomore year at Belmont to his junior year with Maryland. The transfer portal era in college basketball has been defined by a seemingly endless stream of player movement, catalyzed by ludicrous sums of money exchanging hands. Its downstream effects on player evaluation are abundantly evident. With the massive financial incentive to transfer ‘up’ in level, mid-major basketball has never been shallower, and the portal is littered with cases of non-power conference players (especially diminutive scoring guards) going a level too high for their games and being relegated to a reserve role. For every Ja’Kobi Gillespie there are seemingly five times as many players who fall short of expectations once they make the leap to a higher level of competition. In just the past season guards such as Aidan Mahaney, Myles Rice, and Malik Mack come to mind as players who failed to adjust to their new team.

And to be fully transparent, I was skeptical Gillespie’s game would translate to a conference in the Big Ten, which is known for its physicality and deliberate style of play. By transferring from Belmont, Gillespie was leaving one of the most progressive offensive schemes in college basketball, where head Coach Casey Alexander has made high-tempo and robust three-point attempt rates staple characteristics of his teams.  

Alexander’s penchant for constructing elite offenses created a finishing environment disparate from the kind of offenses Gillespie’s new coach, Kevin Willard, had directed over the course of his career. Willard, styling himself as more of a defensively oriented coach, was on the opposite end of the offensive spectrum to Alexander. Per Bart Torvik, Willard-coached teams had only been in the top-100 in adjusted tempo AND three-point attempt rate twice since 2011.

Less ideal offensive circumstances are especially notable in Gillespie’s case because a significant feature that separated him from other portal guards is his abnormal efficiency inside the arc. In the 2023-24 season, Gillespie finished 72.6% at the rim and posted a 63.4% effective field goal percentage, numbers virtually unheard of for any perimeter player. Without an overly dynamic handle or vertical athleticism (Gillespie only converted one of these rim attempts into a dunk), Ja’Kobi seemed acutely prone to experiencing a significant decline in his two-point efficiency. With a precarious outlook as a downhill threat, and having only posted a pedestrian 0.36 3PAr in 23-24, there didn’t seem to be avenues for Gillespie to weather the leap in competition and replicate the production he had enjoyed at Belmont.

The environmental factors at Maryland seemed tailored to confine Gillespie to a role where he’d be caught in between positions, too limited of a downhill threat to function as a lead ballhandler, and too small and limited (volume-wise, at least) of a jumpshooter to scale easily off the ball. What transpired over the next season, though, was one of the more radical transformations I’ve seen a player undergo, and Gillespie adapted to his new context with ease. 

Offensive Development and Transcending Circumstances

The 2024-25 iteration of the Maryland Terrapins endeared themselves to fans early in the season, gaining the nickname of the ‘Crab 5’ for their stellar starting unit, which was as much a byproduct of their lack of depth as it was the talent of this 5-man lineup. Due to Maryland’s weaker reserves, Gillespie was thrust into a new role of primary facilitator, and his pick-and-roll   (+passes) frequency more than tripled, rising from 131 possessions, which accounted for 29.4% of his possessions, to 454 possessions, which accounted for 60.3% (!!) of his team’s possessions. Despite his inexperience as the lead ballhandler and environmental conditions rife with opportunities to log turnovers, Gillespie displayed almost categorical improvement as a playmaker. In fact, the argument could be made that Gillespie’s improved passing acumen was THE driving force for Maryland’s offense.

From 2023-24 to 2024-25, Gillespie improved his assist-to-turnover ratio from 1.72 to 2.52. Gillespie’s turnover economy reaching this level was a massive surprise. A player leaving an offense with more ‘easy buttons’ in Belmont, where there was a bevy of shooters and plenty of open court passing opportunities to relieve pressure from ballhandlers (evidenced by their 80th percentile team AST%), should see their playmaking ability trend in the opposite direction. Maryland’s team 3PAr may have been near the bottom of the country (271st), but Gillespie’s relieving his teammates of playmaking duties ensured that the team’s TO% remained low (21st in the country) and that the threes they did attempt were high-quality shots. The dynamic created by Gillespie monopolizing playmaking responsibilities allowed Selton Miguel and Rodney Rice to have career years from three. This, paired with Gillespie modifying his own shot profile (increasing his 3PAr from 0.36 to 0.54) while increasing his efficiency, made Maryland one of the best three-point shooting teams in the country, finishing 26th in three-point percentage.

For an offense otherwise bereft of an identity, Maryland ascended into the upper echelon, primarily due to Gillespie’s contributions in these two areas. It cannot be understated how unlikely it is for a team this underwhelming in two of the four offensive factors to become a top-30 offense.

Since 2008, there have only been THREE top 30 offenses to pass and shoot from deep as infrequently as Maryland, and not compensate for this by dominating the offensive glass. Like Maryland, these teams connected on their threes at an impressive clip and applied pressure on opposing defenses with their pace. This isn’t a direct evaluation of Gillespie’s game, but playing fast and capitalizing on the ‘micro-advantages’ that develop in the open court, while avoiding the turnover risk typically associated with high-frequency transition teams, is probably the ideal game state. (Tyrese Haliburton and the style he’s injected into the Indiana Pacers is an example of this.)

Although I don’t believe Gillespie is solely responsible for cultivating this offensive environment (Derik Queen was amongst the best in the country at converting defensive rebounds into early offense via hit-aheads and grab-and-gos), the influence he had on Maryland’s style of play is undeniable. And the argument can easily be made that the style of play Gilliespie enabled was Maryland’s only avenue to generating viable offense. Although it is a small sample, in the 318 minutes Gillespie was off the court, Maryland’s offensive rating took a 20-point dip; this on/off differential was in the 99th percentile. 

Defensive Impact

As impressive as Ja’kobi’s offensive impact was, to evaluate his production on each side of the court discretely would be a mistake. Gillespie’s defensive activity not only helped shape Maryland’s defensive identity (which was the foundation of their success) but served as a perfect complement to their offense, which relied heavily on generating early-clock attempts. Gillespie’s 3.5% steal rate ranked 93rd percentile in the country per CBB Analytics, and this turnover generation was made all the more impressive by the fact that accruing steals was of secondary importance to Gillespie’s role within Maryland’s defensive scheme. Maryland’s frontcourt lacked overwhelming height and highly effective rim protectors; to counteract this personnel limitation, Kevin Willard tasked his backcourt with extending their pickup points and applying consistent pressure on opposing ballhandlers.

Gillespie routinely defended the length of the court, preventing opponents from initiating their offense early in the shot clock and alleviating pressure from his back line. Gillespie’s work rate as a perimeter defender helped Maryland finish in the 78th percentile in average defensive possession length per KenPom, meaning that they were amongst the best in the country in forcing opponents deep into the shot clock. To assume such a taxing role while remaining aggressive enough to hunt for steals, all the while avoiding lapses in discipline which could lead to cheap fouls, is outstanding. Despite the degree of difficulty in Ja’Kobi’s role as a point of attack defender, he was in the 97th percentile in steals per personal fouls committed. Combining physical traits such as exceptional lateral quickness, strong and accurate hands, and impressive contact balance, along with a penchant for exploiting ball handlers’ tendencies, leads to his success.

Take the plays below, for example. Maryland is in ‘Ice’ coverage, where Gillespie’s responsibility is to remain on the ‘high side’ of the ball screen and force the ball handler to the baseline. Even though it may not be the ‘correct’ approach, Gillespie understands he has teammates defending in the corner and one pass away, providing a larger margin for error than if the opponent were running an empty pick-and-roll, for example. Trusting his ability to absorb contact with the screener and recover into the play, Gillespie takes advantage of both ballhandlers’ need to process the play developing in front of them, and backtaps their handle loose.

Beating Expectations

By now, it’s probably clear how big a fan I am of Gillespie’s game and his translatability to the NBA. Still, I’d be remiss to not mention the uphill climb any player of his stature faces in cementing themselves as an NBA mainstay. A simple query of NBA players to come through the NCAA ≤ 6’2 and possess a free throw rate ≤ 0.25 to have played any minutes in the NBA yields fairly bleak returns. Of the 95 seasons played and 56 unique players to fall into this query, only 12 have played more than 2000 NBA minutes to date, with the highlighted names representing players who hit these thresholds in their pre-NCAA season.

Most smaller guards are acquired with offensive value in mind; forgoing rim-pressure as part of their offensive repertoire is a death knell to the majority of backcourt players. The list of players within the query to fall short of the 2000 minutes threshold is littered with some of college basketball’s favorite rim-averse gunners, from Andrew Goudelock to Kyle Guy, players who were unequivocally not NBA-caliber talents. So if this list, comprised primarily of G League mainstays, evinces that a player with Ja’Kobi Gillespie’s profile more than likely isn’t worth spending ANY amount of draft capital on, what reason is there to believe he is worth a first-round pick?

First, to address Gillespie’s limitations inside the arc, creating a query to see how previous NBA prospects fared in a similar team environment to Gillespie returned interesting results. Examining which players played on teams that finished ranked outside the top-250 in both team AST% and 3PAr, while maintaining similar two-point efficiency to Gillespie on a similar self-created rate (represented by ‘total assist% ≤ 0.40, and two-point True Shooting ≥ 55%) yielded 146 players. The average height of players captured in this query was 6’7, with there only being six players Gillespie’s height or shorter: Justin Robinson, Ray McCallum, Chasson Randle, Mike Williams, Myles Powell, Malcolm Delaney, and Jeff Dowtin.

As you can see, Gillespie’s shot profile, processing, and defensive production are all more palatable than the rest of the group. This prevented him from falling into a negative skill intersection which inhibited the accompanying players’ NBA chances. As suboptimal as Ja’Kobi’s rim pressure may seem, he finished above expectation considering his circumstances, and in all likelihood, the abandoned forays towards the rim were balanced by a lower turnover total. What makes the chances of a player Gillespie’s size sticking in the league so infinitesimally small is how little tolerance teams will have in accommodating lineups these players participate in. This is far from a novel insight, but in a way this exercise has demonstrated how unsuccessful we have been in ascertaining which flaws the league should be especially punitive in judging. As important as it is for these players to provide a scoring punch, contributing to the turnover margin seems to be paramount, from my research. The smaller ‘game manager’ guards who have drastically exceeded expectations, such as Fred Van Vleet and TJ McConnell, may be the most instructive cases of this. 

What the Future Holds

As Gillespie begins his final season with Tennessee, the impact that another, vastly different, team context will have on his production is something I’ll be fascinated to see. Rick Barnes offenses have been maligned in the past for being archaic; while I don’t think this is quite a fair judgment, there is some fairness in criticizing Barnes’ teams for being stylistically inflexible. Taking a look at Barnes’ Tennessee teams over the years reveals an offensive philosophy rooted in exercising control over his players’ decision-making and confining the team to operating within a scheme primarily consisting of set plays.

For all the external gripes with Barnes’ offense, I could see this having a positive effect on Ja’Kobi Gillespie’s development. My prediction would be that Barnes’ habit of deploying players in clearly defined roles will see Ja’Kobi complete his transformation into a full-time point guard and the ‘trigger man’ of this off-ball screen-centric offense. As consistently as Barnes has featured high-volume movement shooters as the focal point of Tennessee’s offenses (a role I see Nate Ament taking on this season), facilitating duties have typically been assigned to one guard. Whether it be Zakai Zeigler, Jordan Bone, or Kennedy Chandler in past years, the responsibility to orchestrate Tennessee’s heavily manicured offense has fallen on the shoulders of one player. While this may result in some early growing pains from Gillespie, as he’s never played in such a deliberate and halfcourt heavy offense, if he’s able to somewhat maintain his finishing efficacy in an environment even less conducive to a player of his stature, he’ll have cemented himself as a bonafide first round pick and perhaps a top 20 player in the 2026 draft class.
