Those four -- who combined for 13 NBA championships, four Most Valuable Player awards, five NBA Finals MVP awards, 59 All-Star appearances and 40 All-NBA selections -- are the leading names on the list of 50 people nominated by the North American Committee for enshrinement next year.
The finalists will be announced during All-Star Weekend in Chicago in February, with the inductees being unveiled during the Final Four in Atlanta in April.
In addition to Bryant, Duncan, Garnett and Bosh, other players nominated for the first time this year include Shawn Marion, Michael Finley, Mark Eaton and Buck Williams. Meanwhile, Chauncey Billups, Mark Jackson, Tim Hardaway, Richard Hamilton, Chris Webber, Ben Wallace and Marcus Camby are among those on the ballot who have been nominated multiple times.
The class, though, will be led by the four stars at the top of it.
Garnett: HOF would mean everything to me
Kevin Garnett discusses what it would mean to him to be inducted into the Basketball Hall of Fame.
Bryant spent his entire 20-year career with the Los Angeles Lakers, partnering first with Shaquille O'Neal and then Pau Gasol to claim five titles and reach seven NBA Finals, all while becoming one of the most prolific scorers in NBA history.
Duncan also spent his entire career with a single franchise, playing 19 seasons for the San Antonio Spurs under coach Gregg Popovich and alongside David Robinson, Tony Parker, Manu Ginobili and Kawhi Leonard.
Garnett, meanwhile, helped usher in the current era of the NBA by agreeing in the summer of 2007 to join Ray Allen and Paul Pierce with the Boston Celtics after spending the first 12 years of his career playing for the Minnesota Timberwolves.
The Celtics would go on to win the NBA title in 2008 and reach the NBA Finals in 2010, where they lost in seven games to Bryant and the Lakers. Their dominance over the Eastern Conference then helped spur Bosh, LeBron James and Dwyane Wade to play together with the Miami Heat starting in 2010.
After winning two titles and reaching the NBA Finals each of the next four seasons with the Heat, Bosh saw his career derailed by recurring issues with blood clots, forcing him to retire in 2016 while still at the peak of his game.
Truly an honor. My career ended earlier than expected and that hurt immensely. To come to this point being nominated for the Hall of Fame with my heroes is truly an amazing feeling. #HOF20 pic.twitter.com/I0dlBgnBoW— Chris Bosh (@chrisbosh) December 19, 2019
There are plenty of other starry names on the list too. Coaches nominated include Rick Adelman, George Karl, Dick Motta and Rudy Tomjanovich from the professional ranks, and Gene Keady, Rollie Massimino, Bob McKillop, Eddie Sutton, Bo Ryan and Jay Wright on the college side.
Women's nominations include first-timers Swin Cash and Tamika Catchings, along with current San Antonio Spurs assistant coach Becky Hammon and Baylor coach Kim Mulkey, who is nominated as a coach and as a player.
Former Chicago Bulls star Toni Kukoc heads the list of international honorees.
