A day after watching his longtime friend and teammate Kevin Garnett go into the Naismith Memorial Basketball Hall of Fame, longtime Boston Celtics star Paul Pierce joined him in Springfield, Massachusetts.

Pierce, along with two-time champion and 11-time All-Star selection Chris Bosh, five-time All-NBA selection Chris Webber and four-time Defensive Player of the Year Ben Wallace, headlined the 2021 Hall of Fame class. The honor was announced the day after Garnett, Duncan and the late Kobe Bryant officially were inducted as part of the 2020 class, which saw its entry delayed because of the COVID-19 pandemic.

Webber had been a finalist in each of the past five years before finally breaking through and getting the selection. Bosh and Pierce were among those who made it in their first year of eligibility.

The other members of the 2021 class are:

• Rick Adelman, longtime NBA coach

• Jay Wright, two-time NCAA champion head coach

• Bill Russell, who won two championships as a coach, for his time on the sideline;

• Yolanda Griffith, WNBA legend

• Lauren Jackson, WNBA legend

• Bob Dandridge, by the veterans committee

• Toni Kukoc, by the international committee

• Pearl Moore, a college basketball legend, by the women's veterans committee;

• Clarence Jenkins, named to the Hall as an Early African-American Pioneer;

• Val Ackerman, former WNBA president

• Cotton Fitzsimmons, longtime NBA coach

• Howard Garfinkel, who created the Five-Star summer camp

Pierce, alongside Garnett and Ray Allen, led the Celtics to the 2008 NBA title, along with winning Finals MVP that same year. He finished with 10 All-Star appearances, four All-NBA team selections and scored more than 26,000 points across his 19 seasons with the Celtics, Brooklyn Nets, Washington Wizards and LA Clippers.

Bosh, who was drafted fourth overall by the Toronto Raptors in 2003, spent seven years with Toronto before joining the Miami Heat as a free agent in 2010, teaming up with LeBron James and Dwyane Wade to win championships in 2012 and '13 and make four straight NBA Finals. He also won a gold medal with Team USA in 2008, though his career was cut short by blood-clot issues that caused him to have to retire in 2017 while still in his prime.

"It was short-lived, in my opinion," Bosh said about his career. "I wanted to play a lot longer; unfortunately it came to an abrupt end. But just looking back on everything I was able to accomplish, all the friends I was able to make, the connections I made, all the memories we were able to make together, that's what's most important."

After being part of one of college basketball's iconic teams as the top recruit of the Fab Five to attend the University of Michigan, Webber, the No. 1 pick in the 1993 NBA draft, was the a five-time All-Star, five-time All-NBA selection and was the NBA Rookie of the Year in 1994. His best years came playing for Adelman with the Sacramento Kings from 1998 to 2005, when he helped lead the Kings to seven of the 10 playoff appearances they've made in the 36 years they have been in Sacramento -- and he was there all four times they have won a playoff series.

Wallace, who went undrafted out of Virginia Union in 1996, developed into one of the best defensive players of all time and was the anchor of the great Detroit Pistons teams of the 2000s that won the title in 2004 and made it to six consecutive Eastern Conference finals. He is tied with Dikembe Mutombo for the most Defensive Player of the Year honors (four) in a career, while he made four All-Star teams, five All-NBA teams and five All-Defensive teams during a career that also saw him play for the Wizards, Orlando Magic, Chicago Bulls and Cleveland Cavaliers.

Adelman made it to two NBA Finals and won more than 1,000 games as a coach with the Portland Trail Blazers, Sacramento Kings, Houston Rockets and Minnesota Timberwolves, while Wright has lifted Villanova back to the top of the college basketball world, winning two titles and making three Final Fours during his time in Philadelphia.

"It's pretty amazing," Wright said. "You showed the picture of all those guys -- Bill Russell, KG, Chris Webber -- and just to be hanging with these guys right now and listening to their stories and being part of the Hall with them, and this class, it's nothing you'd ever even dream of. It's pretty cool."

Russell, obviously one of the greatest players of all time, won a pair of titles as a coach with the Boston Celtics in the late 1960s. He had previously been enshrined as a player in 1975. He becomes the fifth Hall of Famer who'll be inducted as both a player and a coach, joining John Wooden, Lenny Wilkens, Bill Sharman and Tommy Heinsohn.

Jackson was a three-time MVP and won two championships with the Seattle Storm, while Yolanda Griffith was the 1999 WNBA MVP and led the Sacramento Monarchs to the title in 2005.

"I'm very, very proud just to be given an opportunity," Griffith said of her time in the WNBA. "I got drafted in '99, No. 2 pick to the Sacramento Monarchs, and it was a joy because that gave me an opportunity to be back home from playing over in Europe. It gave my family a chance to see me play, finally, on the professional level, and just enjoy playing at that level on the highest level, basically. I enjoyed the ride with the Sacramento Monarchs."

The class will be enshrined on Sept. 11.
