The NBA landscape is dotted with storied rivalries, but few burn as brightly and consistently as the one between the Boston Celtics and the Cleveland Cavaliers. Fueled by iconic players, playoff clashes, and a constant battle for Eastern Conference supremacy, their matchups have delivered countless memorable moments. While many games have contributed to their rich history, certain instances stand out as truly defining, encapsulating the intensity, skill, and sheer drama that this rivalry embodies. This article delves into the top 5 moments that have etched themselves into the annals of Celtics-Cavaliers lore.
5. The Dawn of a New Era: Kyrie Irving’s Block and Game-Winner (October 18, 2017)
The 2017-2018 NBA season opener between the Celtics and Cavaliers was more than just a regular-season game; it was a seismic event that signaled a dramatic shift in the rivalry. Fresh off his blockbuster trade from the Cavaliers to the Celtics, Kyrie Irving was making his highly anticipated debut in the green and white. The game itself was a nail-biter, showcasing the volatile nature of these two franchises. However, it was in the dying moments that the narrative truly solidified.
With the game tied and seconds ticking away, LeBron James drove to the basket, seemingly poised to seal the victory. But in a breathtaking display of defensive intensity, Kyrie Irving, the player who had once been the beneficiary of LeBron’s brilliance, delivered a crucial chase-down block. This defensive gem not only saved the game but set the stage for Irving to then drain the game-winning jump shot on the other end. This moment was symbolic of Irving’s new chapter and his desire to prove he could lead a team to glory, even against his former franchise and mentor.
Statistical Significance: Irving’s game-winner was the exclamation point on a stellar 22-point, 10-assist performance. The block, though not recorded in the stat sheet as a “chase-down block” in the same way we might track it today, was a pivotal defensive play that demonstrably altered the outcome.
4. The Eastern Conference Finals Gauntlet: LeBron’s Dominance and the Celtics’ Resilience (2018 Eastern Conference Finals)
The 2018 Eastern Conference Finals between the Celtics and Cavaliers was a seven-game epic that tested the mettle of both teams. Without their star point guard Isaiah Thomas, who was sidelined with hip issues, the young and inexperienced Celtics squad, led by Al Horford and emerging talents like Jayson Tatum and Jaylen Brown, found themselves up against a seasoned LeBron James and a Cavaliers team that had reached the NBA Finals for four consecutive years. This series became a testament to LeBron’s unparalleled ability to elevate his team, but also showcased the burgeoning potential of Boston.
The series was a seesaw battle, with momentum swinging wildly. The Cavaliers, fueled by LeBron’s Herculean efforts, managed to force a Game 7 in Boston.

Their ability to win two games against the Cavaliers, including a statement victory in Game 3 where they showcased exceptional ball movement and defensive pressure, demonstrated their fight and the foundation they were building for future success. This series, though a loss, was a crucial step in their development.
3. The Block Part Deux: LeBron James’ Iconic Defensive Play (June 7, 2016)
While this moment predates the Celtics-Cavaliers rivalry in its most intense form, it is inextricably linked to the players who would later define it. Game 7 of the 2016 NBA Finals saw the Cleveland Cavaliers, down 3-1 in the series against the dynastic Golden State Warriors, staging a historic comeback. In a pivotal moment, with the game tied at 89 with just under two minutes remaining, Golden State guard Stephen Curry drove to the basket for a potential go-ahead layup.
In one of the most dramatic defensive plays in NBA history, LeBron James, from behind, leaped and swatted Curry’s layup off the backboard. This “The Block” was not only a game-saving defensive masterpiece but a symbol of the Cavaliers’ relentless pursuit of their first NBA championship. It shifted the momentum irrevocably and paved the way for Kyrie Irving’s championship-clinching three-pointer moments later. The sheer athleticism, timing, and desperation displayed by James in this play are etched in basketball folklore.
Impact on Legacy: This block is often cited as the defining moment of LeBron James’ career and a crucial catalyst for the Cavaliers finally breaking their championship drought. It cemented his status as one of the greatest players of all time and set the stage for his return to Cleveland, which would later fuel this specific rivalry.
2. The East Runs Through Cleveland: Cavaliers Sweep the Celtics (2017 Eastern Conference Finals)
Following their thrilling 2016 championship, the Cleveland Cavaliers were a juggernaut. The Boston Celtics, having endured a strong regular season and advanced through the playoffs, found themselves facing a seemingly insurmountable challenge in the 2017 Eastern Conference Finals. The series was billed as a clash of titans, with Isaiah Thomas leading a young Celtics squad against the formidable trio of LeBron James, Kyrie Irving, and Kevin Love.
However, the reality on the court was a stark demonstration of Cleveland’s dominance. The Cavaliers swept the Celtics 4-0, with LeBron James delivering an almost flawless performance. He averaged a triple-double for the series, showcasing his all-around brilliance and leadership.
