1. The Efficiency Gap: Outdueling the Cavaliers’ Star Power

The most telling aspect of the Celtics' victory was how effectively Jaylen Brown maintained his scoring efficiency against a defense built around slowing down elite wings. While the specific shooting splits for the series are often buried in deep analytics, Brown’s overall playoff True Shooting Percentage (TS%) in 2024 was "hyper efficient" at over 61.2% through the first two rounds, a mark that speaks to his shot selection and dominance.

This efficiency was particularly critical when compared to the Cavaliers' primary star, Donovan Mitchell. Although Mitchell was spectacular, averaging a scorching 31.7 points, 6.3 rebounds, and 5.3 assists in the three games he played, his absence in Games 4 and 5 due to injury proved fatal. Brown, on the other hand, was available and dominant in every contest, ensuring the Celtics never faltered. Brown’s consistency, combined with the presence of Jayson Tatum, proved to be an insurmountable advantage over the short-handed Cavaliers.

2. The Iron Man Factor: Consistency in the Face of Adversity

In the modern NBA playoffs, availability is often the best ability. The Cleveland Cavaliers suffered significant blows, with Donovan Mitchell sitting out the final two games and Jarrett Allen missing the entire series due to injury. This left the bulk of the offensive and defensive responsibility on players like Darius Garland, Evan Mobley, and Caris LeVert.

Jaylen Brown’s physical durability and consistent presence were a stark contrast. He played in all five games, logging heavy minutes and maintaining his production. This reliability allowed the Celtics to maintain their offensive rhythm and defensive intensity, especially in the pivotal games at the Rocket Mortgage FieldHouse in Cleveland. Brown’s ability to put pressure on the rim and stretch the floor provided the space needed for teammates like Al Horford and Derrick White to contribute with timely three-point shooting, ultimately overwhelming the Cavaliers' depleted rotation.

3. The Okoro-Brown Matchup: A History of Defensive Struggle

The individual matchup between Jaylen Brown and Cavaliers defensive stopper Isaac Okoro has been a fascinating subplot in their rivalry. Okoro is known for his ability to lock down elite wings, and he has had historical success against Brown, notably holding him to a 1-for-11 shooting night in a past regular-season game.

However, in the 2024 ECSF, Brown showcased his growth, navigating Okoro’s tenacious defense with greater maturity and variety in his offensive arsenal. He utilized screens more effectively, attacked the closeouts with authority, and relied on his mid-range game when the three-point line was contested. While Okoro provided resistance, Brown’s overall series average of 23.4 PPG demonstrates his ability to overcome even the most focused defensive game plans, proving he can win the individual battle when it matters most in the postseason.

4. Playmaking Pressure and the Triple-Double Flashback

While Jaylen Brown is primarily known for his scoring, his underrated playmaking ability has often surfaced against the Cavaliers. In a notable past regular-season game, Brown recorded a rare triple-double against Cleveland, finishing with 19 points, 12 rebounds, and 11 assists, showcasing his ability to impact the game beyond scoring.

In the 2024 ECSF, though his assist numbers (2.8 APG) were modest, his presence as a primary ball-handler was key. He consistently drew double-teams and forced rotations, which created open looks for Boston’s shooters. This pressure, especially when driving against the interior defense of Evan Mobley, was instrumental in preventing the Cavaliers from collapsing their defense entirely on Jayson Tatum. Brown’s threat as a scorer unlocked the entire Celtics offense, making him a dual-threat weapon that the Cavaliers simply could not contain without their full roster.

5. Setting the Tone for a Championship Run

The 4-1 series victory over the Cavaliers was more than just a win; it was a statement about the Celtics' championship pedigree. For Jaylen Brown, it was a crucial step in his journey to becoming a Finals MVP. His consistent, high-level production against Cleveland demonstrated his readiness to lead a deep playoff run.

The series served as a proving ground, showing that Brown could shoulder a significant scoring load and maintain his composure and efficiency under the intense pressure of the NBA playoffs. His ability to perform at a peak level, even as the Cavaliers threw different defensive looks at him, confirmed his status as an indispensable cornerstone of the Celtics franchise. The lessons learned and the confidence gained from dismantling a solid team like Cleveland directly contributed to the team's momentum, which carried them through the rest of the 2024 NBA Playoffs and ultimately to the Larry O'Brien trophy.
