The final NBA on TNT commentating roster included Kevin Harlan, Brian Anderson, Ian Eagle, and Spero Dedes for play-by-play. Harlan and Anderson normally called Thursday games, while the latter also usually worked Tuesday games with Eagle. Dedes filled in occasionally for both Tuesday and Thursday games, but mainly called games for TNT during the NBA playoffs. Fox Sports' Gus Johnson joined the rotation for the NBA playoffs.
Reggie Miller and Stan Van Gundy were the top color commentators for most games. Other analysts like Jim Jackson, Grant Hill, Candace Parker, and Greg Anthony contributed for select games.
The sideline reporter role was rotated between Allie LaForce, Jared Greenberg, Lauren Jbara, Stephanie Ready and Taylor Rooks. Dennis Scott joined the rotation for the NBA playoffs.
Ernie Johnson controlled the main studio hosting duties on Thursdays, with Bleacher Report's Adam Lefkoe serving that role on Tuesdays. Occasionally, whenever Johnson was away for other assignments, most notably March Madness, or personal reasons, Lefkoe filled in for Johnson. Studio coverage was usually contributed by Shaquille O'Neal, Kenny Smith, and Charles Barkley on Thursdays, with O'Neal, Candace Parker, and Vince Carter contributing on Tuesdays. Parker and Carter, along with Hill among other analysts contributed to the studio show at times.
Prior to his death on December 15, 2016, Craig Sager[57] served a variety of roles on TNT, most prominently as a sideline reporter. Sager was usually paired with Cheryl Miller on most doubleheaders from 1997 to 2013.
Before he was hired as head coach of the Golden State Warriors in 2014, Steve Kerr was the primary game analyst on TNT. Kerr served that role from 2003 to 2006, and again from 2010 to 2014; in between he served as general manager of the Phoenix Suns.
Prior to leaving TNT before the 2021 NBA playoffs, Hall of Fame forward Chris Webber had been tapped as a co-lead analyst, and fill-in studio analyst from 2008 to 2021. Webber and TNT had parted ways without any contract renewal negotiations.
Miami Heat legend Dwyane Wade was part of the Tuesday studio team for three seasons beginning in 2019 but left to pursue other business ventures. Crawford replaced Wade during the 2022–23 season.
Doug Collins[58] was the secondary analyst on TNT; he was also the lead analyst in his first stint with the network from 1989 to 1995, pairing with the likes of Bob Neal, Ron Thulin and Pete Van Wieren. In his second stint from 2003 to 2010, he was usually paired with Harlan during the regular season but was also paired with Albert during the NBA All-Star Game and the conference finals.
The original voice of the NBA on TNT was Bob Neal, who worked with the network from 1989 to 1995; he was also the original voice of the NBA on TBS. Other announcers who worked for TNT include Rick Barry, Hubie Brown, Dick Stockton,[59] Verne Lundquist, Chuck Daly, Danny Ainge, Reggie Theus, Rex Chapman, John Thompson, Jeff Van Gundy, P. J. Carlesimo, Gary Bender, Matt Devlin, Joel Meyers and Kevin Calabro.
Several prominent NBA analysts chose TNT over ABC or ESPN, such as Doug Collins and Charles Barkley (Barkley was not only approached by ABC about an NBA studio job in 2002 but as also rumored to have been approached for a job on Monday Night Football). Reggie Miller was also sought out by ABC and ESPN, only to go to TNT.
The biggest acquisition TNT made, once sought out by ABC and ESPN, was Marv Albert. After the 2002 NBA Finals, Albert, along with Bob Costas, essentially a free agent, was a candidate for the lead spot on The NBA on ABC (which ultimately went to Brad Nessler). As Costas elected to remain with NBC, Albert, hired by TNT in 1999, decided to stay with the network.[60] Some attributed this to TNT having given Albert his first chance to be on national television after the sex scandal that led to his firing at NBC. Albert and Mike Fratello—both of whom worked as a team in the NBA on NBC's early years—would ultimately reunite on TNT. Pam Oliver, the then-lead sideline reporter for the NFL on Fox, joined Turner Sports in 2004 as she would only be on during the NBA playoffs, a role she fulfilled until 2009.
