The 2019 NBA Summer League in Las Vegas was the first real look at the Chicago Bulls' new trajectory. With a roster headlined by rookie guard Coby White and second-round steal Daniel Gafford, the team had the ingredients for a promising July campaign. For the busy practical observer, however, the most valuable lesson from the Chicago Bulls Summer League 2019 roster isn't the win-loss record—it is the structural mistakes teams regularly make when assembling and evaluating these squads. Here is an editorial breakdown of the common pitfalls and the smarter alternatives that define a winning Summer League philosophy.
The Empty Scoring Stare
Mistake: Assuming gaudy point totals in the box score translate directly to NBA readiness. Coby White carried a heavy scoring load, averaging over 15 points per game, but his efficiency (shooting under 40 percent from the field) was a red flag that many casual fans overlooked. The smarter alternative is dissecting how those points were generated. Were they coming from isolation possessions against weak competition, or was the offense creating open looks through structured movement? The Bulls' roster construction often forced White to create miracles, rather than setting him up for sustainable success through spacing and screen actions. The volume was a mirage; the process was the real data point.
The Gap Fillers: Precision in Role Selection
A core mistake in Summer League scouting is treating the roster like an all-star exhibition where everyone chucks shots. The smarter alternative is a workshop mentality where every player is a specific tool. The 2019 Bulls roster had a clear rim-running gap that was perfectly filled by Daniel Gafford, and a shooting void plugged by Matt Thomas. However, the squad struggled to find a consistent wing defender and secondary playmaker. Just as a pack of shims provides a variety of thicknesses for different spaces, the front office must ensure they have the right player type for every situational need on the floor. When a team misses on these precise fits, rotations wobble and evaluations become muddied by poor fit rather than raw talent.
Looking at the Bulls specifically, the lack of a reliable secondary ball-handler next to White meant the offense stagnated when he sat. A smarter approach in 2019 would have been targeting a true combo guard in the unsigned pool instead of relying on natural shooting guards to create off the dribble. This act of shimming the roster directly impacts how the coaching staff grades young talent.
The Summer League Hero Trap
Mistake: Overvaluing contract-year players and undrafted free agents who put up massive numbers in a chaotic environment. Walt Lemon Jr. and Brandon Sampson exploded for high-scoring outings, including a 32-point game from Sampson. The smarter alternative is realizing that these performances often happen in a vacuum of low defensive accountability and loose offensive schemes. The Bulls roster featured several players who dominated the box score but lacked the specific transferable skills (defensive awareness, passing vision, consistent shooting mechanics) to survive in an NBA rotation. The ability to score in isolation in a July game rarely translates to running a pro-level offense in October.
Veteran Bright Spots Versus Developmental Ceilings
The inclusion of Ryan Arcidiacono provided the 2019 summer team with a steady floor general. Mistake: Letting the veteran dictate the tempo to the point where young players defer entirely. The smarter alternative is using the veteran as a defensive coordinator and a culture-setter, while forcing the rookies into the fire as primary decision-makers. The Bulls often looked their best when Arcidiacono was setting the table, but the lynchpin of a successful Summer League roster is letting the draft picks learn by making mistakes. If the roster is built to win July games rather than develop October players, the evaluation is compromised from the start.
Defensive Integrity as a Roster Requirement
The 2019 Bulls Summer League roster was specifically vulnerable to perimeter penetration. Mistake: Prioritizing offensive firepower over two-way potential, leaving the defense scrambling on switches and rotations. The smarter alternative is ensuring the roster has multiple point-of-attack stoppers who can sustain pressure for a full game. While Gafford protected the rim admirably, the guards on the Bulls roster were regularly beaten off the dribble. Building a Summer League team without a defensive identity is a guaranteed way to blow double-digit leads and develop bad habits in young players. A balanced roster must include at least one or two defensive specialists who understand team coverage schemes and can hold the line while the scorers find their rhythm.
