Knicks vs. Celtics Playoff Showdown: Fans Bring the Noise Outside the Arena

By Daniel Richardson, Editor-in-Chief of Archysport

BOSTON — The rivalry between the New York Knicks and Boston Celtics has always been fierce on the court, but in the streets outside TD Garden, the passion of the fans has reached a fever pitch. As the Knicks marched into the Eastern Conference Finals for the first time in 25 years with a dominant 119-81 victory over the Celtics in Game 6 on April 26, 2026, the atmosphere outside the arena was electric—filled with chants, taunts, and the kind of energy that only playoff basketball can inspire.

The Scene Outside TD Garden

Long before tipoff, fans from both cities descended on Boston’s North Station neighborhood, turning the area into a sea of blue and orange for the Knicks and green and white for the Celtics. The rivalry, which dates back to the 1950s, has seen its share of iconic moments, but the intensity of the 2026 playoff series has brought a new level of fan engagement—both inside and outside the arena.

Videos circulating on social media showed groups of Knicks fans clashing with Celtics supporters in good-natured (and sometimes not-so-good-natured) banter. One clip, verified by multiple sources, captured a group of Knicks fans chanting, “25 years! 25 years!”—a reference to the franchise’s long drought without an Eastern Conference Finals appearance. Celtics fans responded with their own rallying cry: “Beat L.A.! Beat L.A.!”—a nod to their hopes of facing the Los Angeles Lakers in the NBA Finals.

Local authorities reported no major incidents, but the Boston Police Department confirmed an increased presence around TD Garden to manage the crowds. “The energy is incredible, but we want everyone to stay safe,” a spokesperson said. “This is playoff basketball, and the fans are bringing the noise.”

Why This Series Matters

The Knicks’ victory in Game 6 wasn’t just a win—it was a statement. After years of playoff disappointments, New York’s resurgence under head coach Tom Thibodeau has been nothing short of remarkable. The team’s defense, led by Mitchell Robinson and OG Anunoby, has stifled opponents all season, and their ability to close out the Celtics in dominant fashion sent shockwaves through the NBA.

For the Celtics, the loss marked the end of a one-year title reign. After winning the 2025 NBA Championship, Boston entered the 2026 playoffs as the top seed in the East, but their struggles against the Knicks’ physical play exposed vulnerabilities. Jayson Tatum, who had been dealing with a nagging ankle injury, was held to just 14 points in Game 6, while Jaylen Brown struggled to find his rhythm.

The Knicks, meanwhile, have been on a mission. Jalen Brunson, who finished with a team-high 31 points in their February 8 victory over the Celtics, has been the engine of their offense, while Julius Randle’s leadership has been crucial in high-pressure moments. Their 119-81 win in Game 6 was the largest margin of victory in a series-clinching game in Knicks history, a fact that has only added fuel to the fire for their fans.

The Fan Experience: More Than Just a Game

For many fans, the playoffs are about more than just basketball—they’re about identity, pride, and community. Knicks fans, in particular, have endured decades of heartbreak, from the Patrick Ewing era to the more recent struggles. The team’s resurgence has reignited a sense of hope in New York, and the fanbase has responded with unbridled enthusiasm.

“This is what we’ve been waiting for,” said Marcus Rivera, a lifelong Knicks fan who traveled from Queens to Boston for Game 6. “We’ve been through the ups and downs, but this team is different. They play hard, they play together, and they’re not afraid of anybody.”

Celtics fans, are grappling with the reality of their team’s early exit. While the loss stings, the rivalry with the Knicks has always been a source of pride for Boston. “We’ll be back,” said Sarah O’Connor, a Celtics season ticket holder. “This isn’t the end. The Knicks are solid, but we’re better. Next year, we’ll get our revenge.”

What’s Next for the Knicks and Celtics?

The Knicks will now advance to the Eastern Conference Finals, where they’ll face the winner of the Milwaukee Bucks and Indiana Pacers series. The matchup is expected to be a physical battle, with both teams boasting strong defenses and elite scorers. For New York, the goal is clear: end the franchise’s 50-year championship drought.

The Celtics, meanwhile, will head into the offseason with questions about their future. Will they make changes to their roster? Can they address their struggles against physical teams like the Knicks? One thing is certain: the rivalry between these two historic franchises is far from over.
