BOSTON — Jayson Tatum continued Boston’s Banner 18 celebration by scoring 37 points and making eight of the Celtics’ NBA record-tying 29 3-pointers on Tuesday as Boston ran away with a 132-109 victory over the New York Knicks on opening night.

Derrick White scored 24 points, Jaylen Brown added 23, and Tatum had 10 assists for the defending champions, who raised their NBA-most 18th championship banner to the rafters before the game. Boston led by as many as 35 points before missing its last 13 3-point attempts while trying to break the record.

Jalen Brunson scored 22 points for New York, and new addition Karl-Anthony Towns had just 12 points and seven rebounds.

With the Celtics leading by more than 20 points early in the third quarter, the TD Garden crowd’s attention strayed from the basketball game and it began chanting “Yankees Suck!”

TAKEAWAYS

The new-look Knicks were supposed to be the biggest threat to the Celtics in the Eastern Conference, but even after adding Towns and Mikal Bridges over the summer, they were no match for the team that finished 14 games in front last season.

KEY STAT

The Celtics hit their 29th 3-pointer early in the fourth quarter, then fired up two long airballs and 13 misses in a row from beyond the arc as they tried to break the record set in 2020 by Milwaukee. The crowd chanted “One more 3!” in the final minutes, but on Boston’s last possession, Payton Pritchard dribbled out the shot clock without making another attempt.

BANNER CELEBRATION

After the Boston Celtics received their diamond-, emerald- and parquet-encrusted championship rings and before the franchise’s 18th banner was raised to the rafters, Tatum grabbed a microphone to say a few words to the geeked-up crowd.

“Enjoy this moment together,” he told the fans who filled the TD Garden for the first meaningful Celtics game since their Game 5 victory over Dallas in the NBA Finals clinched their unprecedented 18th title. “Let’s do it again.”

The Celtics then gathered where so many of their predecessors had and raised the “2024 World Champions” banner to the crowded rafters.

Six-time champion Bob Cousy and 1981 NBA Finals MVP Cedric Maxwell were on hand for the pregame ceremony, coming out to applause before Paul Pierce – accompanied by fellow 2008 champions Kevin Garnett and Ray Allen – brought out the 2024 trophy. It was placed on a table surrounded by the championship rings.

Owner Wyc Grousbeck handed out the baubles, with NBA Commissioner Adam Silver congratulating the players as they walked out between the numbers of a giant, golden “18.” Coach Joe Mazzulla dropped to his knees to give the parquet floor a kiss before receiving his ring.

The centerpiece of the ring is a shamrock and “Celtics” against a field of emeralds. The top can be removed to reveal a piece of the famous floor, painted green and white with the 106-88 score of the June 17 clincher against the Mavericks. Also unveiled is an image of the championship banner, surrounded by the engraved numbers of each player on the roster.

The exterior of the ring is encircled with the years of the franchise’s 18 NBA titles. On one side is a depiction of the Larry O’Brien Trophy and the team’s 80-21 overall record in 2023-24; on the other is the player’s name, number and the slogan “Whatever It Takes” on a background of the parquet pattern etched into the gold.

The rings have 15 total carats of white diamonds to represent the 15 teams in the Eastern Conference. There are 16 emerald-cut diamonds for the team’s 16 playoff victories, along with the words “WORLD CHAMPIONS” on the inner bezel.

The outer bezel has 18 larger diamonds for the team’s 18 titles – one more than the archrival Lakers have won in Los Angeles and Minneapolis.

The sold-out crowd arrived early to see the Celtics take the court in special warm-up jackets trimmed in gold, with 18 championship trophies embroidered on the sleeve. Some of the players paused their shooting to watch the video tracing their title journey, from the drafting of Brown and Tatum through the acquisition of Jrue Holiday and Kristaps Porzingis.

Another video featured highlights of Havlicek and Russell winning titles in the 1950s and ’60s through the pandemonium of the team’s victory parade last spring.
