Early coaching career (1989–1997) In the
CBA, Musselman posted a 270–122 record (.688), marking the second highest winning percentage in league history behind
George Karl, who coached for five seasons in the CBA. Musselman began his CBA career in 1988 as the general manager of the
Rapid City Thrillers, a franchise his father Bill had coached to three consecutive CBA titles during the 1980s. His first week on the job, he hired
Flip Saunders as the team's head coach. Saunders, who was recruited by
Bill Musselman when Bill was the head coach at the
University of Minnesota during the early 1970s, would go on to be one of the winningest coaches in CBA history before moving to the NBA as coach of the
Minnesota Timberwolves. In the 1989–90 season, at age 24, Musselman became the Thrillers head coach. He holds the highest winning percentage in league history.
Orlando Magic, Atlanta Hawks assistant (1998–2002) Musselman was an assistant coach for the
Orlando Magic from 1998 to 2000 under
Chuck Daly and
Doc Rivers who would go on to be named NBA Coach of the Year in the 1999–00 season, then also for the
Atlanta Hawks from 2000 to 2002 under
Lon Kruger.
Golden State Warriors (2002–2004) In 2002, Musselman was named the head coach of the
Golden State Warriors, a position he held for two years. He finished as runner-up to San Antonio's
Gregg Popovich in
NBA Coach of the Year Award voting in 2002–2003 with 231 points, including 26 first-place votes. That season, under Musselman's guidance, the Warriors, for the first time in nearly a decade, reached the .500 mark late in the season, holding a record of 30–30 on March 4, 2003. In Musselman's rookie season, his club finished 38–44, the most wins in more than 10 years. Despite numerous injuries and the loss of the team's top two players in
Gilbert Arenas (signed with Washington) and
Antawn Jamison (traded to Dallas), the team still finished 37–45 under his direction during the 2003–2004 season. In two seasons as head coach in Golden State, Musselman compiled a 75–89 record. Nevertheless, he was let go after the 2004 season ended when
Chris Mullin took over as the team's general manager. Musselman's .457 winning percentage with Golden State ranks 10th all-time among Warriors coaches, behind
Steve Kerr (.709 through 2019–2020), Neil Johnson (.617),
Frank McGuire (.613),
George Senesky (.551),
Bill Sharman (.534),
Al Attles (.518),
Don Nelson (.487),
Mark Jackson (.473) and George Lee (.470).
Memphis Grizzlies assistant (2004–2006) After his two seasons as head coach of the
Golden State Warriors, Musselman was an assistant coach for the
Memphis Grizzlies under
Mike Fratello from 2004 to 2006. At the time, Musselman said, "Alcohol has never been a big part of my life. I don't allow it in my house. My sons have never seen me take a sip of anything." According to , a sports columnist for
The Sacramento Bee, "[Musselman] drinks so infrequently, in fact, that he can count the number of beers he consumes per month." In the first month of the season (November 2006) with Musselman at the helm, the Kings went 8–5. But the team slumped in December and January, posting a 10–21 record before going 7–6 in February 2007. The Kings finished 33–49 on the season. Musselman was fired by Sacramento President of Basketball Operations
Geoff Petrie on April 20, 2007.
NBA D-League (2010–2012) On August 11, 2010, Musselman was named head coach of the
NBA Development League's
Reno Bighorns. Under his watch, several players, including
Marcus Landry,
Jeremy Lin,
Courtney Fortson, Donald Sloan and
Hassan Whiteside were called up to the NBA and the Bighorns finished 34–16 and first in the D-League Western Conference. Musselman was named head coach of the
Los Angeles D-Fenders on August 18, 2011.
Sports Illustrated called Musselman one of the "best teachers" in the D-League. During the 2011–12 season, he guided the team to a 38–12 record, the best mark in league history. The D-Fenders, who finished with the best defensive FG percentage in the league, advanced to the D-League finals before losing to the Austin Toros, in a three-game series. In April 2012, Musselman was named the 2011–12 D-League Coach of the Year. A month later, in May 2012, the D-Fenders were named the 2011–12 NBA D-League Development Champion, which recognizes "the team that best embodies the NBA D-League's goals of developing NBA basketball talent via call-ups and assignments."
Arizona State assistant (2012–2014) On August 30, 2012,
Andy Katz reported on ESPN.com's College Basketball Nation Blog that
Arizona State University was in talks to hire Musselman as an assistant coach on
Herb Sendek's staff. On September 2, 2012, Katz confirmed Musselman's hiring, describing it as a "bold move" and a "coup" for Sendek. Former NBA coach
Jeff Van Gundy predicted that Musselman will be an excellent recruiter "because of his competitive nature and what he has to sell. This is a guy who can tell kids exactly what it takes to play in the NBA." Fifteen games into Arizona State's 2012–13 season, ESPN's
Andy Katz wrote that "It's hard to ignore the difference [guard Jahii] Carson and assistant coach Eric Musselman are making at Arizona State." According to Katz, "The Sun Devils were painful to watch last season. Now, ASU has multiple options and while it still grinds out wins (see OT game in the 50s to beat Utah), the Sun Devils are 2–0 in the Pac-12 and 13–2 heading to the Oregon schools." On January 9, 2013, ESPN's Jason King wrote that "adding former NBA head coach Eric Musselman...to his staff has also been a huge plus for Sendek and his players." Quoted in King's story, Arizona State center
Jordan Bachynski said, "When [Musselman and Greer] speak, guys listen, just because they have that credibility from being in the league. The way they approach the game … it's no BS. They say, 'This is how it's done. If you don't like it, you're not going to play.'" In a radio interview after the 2012–13 season, Arizona State athletic director Steve Patterson said, "I think Eric's going to have opportunities to look at head coaching jobs. He's a very qualified coach. He did a great job, I think, teaching and working here." In a March 26, 2013, post on the
ESPN Los Angeles UCLA blog, Peter Yoon described Musselman as one of the "best under-the-radar candidates out there." In May 2013, he was promoted to associate head coach. Musselman resigned from Sendek's staff in April 2014. In two seasons with the Sun Devils, Musselman helped ASU to the NIT Tournament in 2013 and the NCAA tournament in 2014. The team went 21–12 in both seasons.
LSU assistant (2014–2015) Following the 2013–14 season, Musselman was a candidate for the head coaching position at the
University of California, Berkeley, the
University of South Florida and
Oregon State University. In June 2014, Musselman became associate head coach at
LSU under
Johnny Jones.
Nevada (2015–19) On March 25, 2015, the
University of Nevada, Reno hired Musselman as head coach for the
Nevada Wolf Pack team. In early March 2016, Bleacher Report named Musselman the Mountain West Coach of the Year after guiding the Wolf Pack to an 18–12 record, a 9-win improvement over the previous season. The team's winning percentage jumped from 31 to 60, which ranked as the 11th best improvement nationally. Following the 2015–16 season, Nevada was invited to play in the
College Basketball Invitational (CBI), winning its first three games to improve its season record to 21–12 and advance to the CBI championship series vs
Morehead State. According to Chris Murray, a reporter who covered the team for the
Reno Gazette-Journal, "No coach in Nevada basketball history has done a better job of getting everything out of the talent on the roster. It might be the best coaching job in Wolf Pack hoops history." Nevada's 2016 recruiting class was ranked as the 35th best in the nation by 247Sports. Musselman's 2016–17 Wolf Pack team went 14–4 in conference play to win the Mountain West regular season title. The team also won the 2017 MWC postseason tournament championship to earn a bid in the NCAA men's basketball tournament. Nevada finished 28–7 overall for the season, tied for the second-most wins in school history. In December 2017, Musselman's Nevada team was ranked in the top 25, the first time since 2007 that the Wolf Pack had ranked among the top 25 teams nationally. Musselman was named 2017–18 Mountain West Coach of the Year after guiding the Wolf Pack to a 15–3 conference record and the
MWC regular season title. He was also named the Coach of the Year for District 17 by the
National Association of Basketball Coaches. The team set a school record for most wins in a season. In March 2018, Nevada was announced as an at-large selection for the
NCAA men's basketball tournament as a seventh seed. In their first-round game, the Wolf Pack came back from 14 points down to defeat
Texas, 87–83. In Round 2, Nevada rallied from a 22-point deficit to upset second-seeded
Cincinnati, 75–73, propelling the Wolf Pack to its second Sweet 16 appearance in school history. During the 2017–18 season, Nevada finished 12–3 in true road games. Those 12 victories were a single-season school record and tied for most in the country. In May 2018 Musselman and staff signed
ESPN's 31st ranked recruit in the 2018 class
Jordan Brown. Brown became the highest-ranked recruit to commit to Nevada since Reno native Luke Babbitt pledged to play for his local school in 2008. On September 5, 2018, the Nevada athletics department announced that season tickets for the upcoming men's basketball season were officially sold out. To start the 2018–19 season, Nevada, Reno was ranked #7 in the preseason
Associated Press poll and #9 in the
USA Today Coaches Poll. It is the highest ranking in school history for the Wolf Pack. The previous top ranking was #9 on February 26, 2007. Additionally, the #7 ranking was the highest preseason ranking in Mountain West Conference history. The Nevada Wolf Pack finished the year ranked in the Associated Press Top 25 all 20 weeks of the college basketball season, with the highest ranking in school history coming in week 4 with a #5 AP ranking. On November 6, Nevada opened the season with an 86–70 victory over BYU. Caroline scored a game-high 25 points, with 21 coming in the second half. Nevada opened the season with the only starting lineup in college basketball consisting of all fifth-year seniors. On November 27, the Wolf Pack avenged their Sweet 16 loss in March to Loyola-Chicago by defeating Loyola, 79–65, in Chicago. The Pack, now ranked No. 5 in the country, was led by Caleb Martin (21 points) and Cody Martin (20 points). A week later, Nevada, Reno rallied in the 2nd half to defeat #20
Arizona State 72–66 in the
Staples Center in
Los Angeles, California. In front of the 12th-largest crowd in
Lawlor Events Center History, the Wolf Pack honored its Seniors beating San Diego State 81–53, and earning its third straight Mountain West Conference regular season title. The Pack became the third team in Mountain West Conference history to win three straight regular season conference titles. Nevada's 2018–19 season shattered the all-time attendance record at
Lawlor Events Center. The season total of 163,169 broke the former record set in 2005–06 of 150,674, and doing it in 3 less games. Additionally, the average home game attendance of 10,878, broke the record set previous year (2017–18), of 9,048. Musselman joined
Mark Few (
Gonzaga),
Dave Rose (
BYU),
Steve Fisher (
SDSU),
Steve Alford (
New Mexico), and
Shaka Smart (
VCU), as recent
mid-major coaches with four-year spans of 25+ wins per season, 3+ tournament appearances, 2+ tournament wins, and at least one week in AP Top 10. After finishing the year with an overall record of 29–5, Musselman received one vote for AP Coach of the Year (tied 11th).
Arkansas (2019–2024) Musselman was named
Arkansas head coach on April 7, 2019. His team got off to an 8–0 start heading into December, the school's best start to a season since the
1997–98 season. The
Razorbacks went 11–1 in non-conference play going in to their conference schedule. They headed into SEC play with a 71–64 win on the road at
Indiana University. Arkansas defeated
TCU 78–67 at home in the mid season
SEC vs Big 12 Challenge. Arkansas at that point had gone 3–3 in SEC play with wins over
Vandy and
Texas A&M at home, and
Ole Miss on the road. Losses were to
LSU and
MSU on the road, and a loss at home to
Kentucky. Arkansas was 16–5 (4–4) when they lost their 2nd leading scorer for a five-game stretch, where they posted a 0–5 record. At full strength over the final six games, the Razorbacks finished the season 4–2. Musselman, in his first year at Arkansas recruited the fifth and sixth-ranked recruiting class in the nation according to ESPN.com and 247sports.com respectively. The season was cut short after a Wednesday victory at the
2020 SEC tournament due to
COVID-19 pandemic concerns. The Razorbacks ended their season with a 20–12 record overall marking Musselman's fifth straight season with 20 or more wins. Following the 2019–20 season, Musselman and staff reeled in the No. 3 ranked transfer recruiting class after three top 25 ranked graduate transfers signed with the Razorbacks. Late in the 2020–21 season, his Razorbacks cracked the Top 25 for the first time since January 2018 and then hosted No. 6
Alabama as the No. 20 ranked team, the first matchup of ranked teams inside
Bud Walton Arena since February 1998. On March 8, 2021, the Razorbacks entered the top 10 of the AP poll for the first time since February 1995, checking in at No. 8 heading into the postseason.

Texas Tech. Musselman ended the Cinderella run of 15-seed
Oral Roberts on March 27, 2021, to advance Arkansas to its first Elite 8 since 1995. The Razorbacks finished the season ranked #10 in the final AP Men's Basketball Poll and #6 in the USA Today Coaches Poll. On February 8, 2022, his team knocked off No. 1
Auburn in front of a then Bud Walton Arena record 20,327 in attendance. As Arkansas had not beaten a number 1 team at BWA, the students rushed the court, resulting in Arkansas paying a $250,000 fine. Arkansas entered the
2022 NCAA tournament as #4 seed. Arkansas beat
New Mexico State to be the only SEC program to advance to the Sweet 16 of the 2022 NCAA tournament. Musselman followed that by knocking off #1 overall ranked
Gonzaga to advance to the Elite 8, making the first time an Arkansas coach took the Razorbacks to back-to-back Elite 8 appearances since Nolan Richardson in 1994 and 1995. The Razorbacks would fall in the Elite 8 to
Duke in head coach
Mike Krzyzewski's 43rd and final season. Arkansas finished ranked #17 in the final AP Poll and #8 in the final USA Today Coaches Poll. His coaching career at Arkansas was further propelled into success with his 2022 recruiting class, which featured several five-star recruits like
Anthony Black (basketball),
Nick Smith Jr., and Jordan Walsh. On March 18, 2023, Musselman's 8th-seeded Razorbacks knocked off a No. 1 seed and defending national champion
Kansas in the

UConn in the regional semifinals in Las Vegas. In his fifth season, Arkansas struggled throughout SEC play after beating
Duke in the non-conference, breaking the Bud Walton Arena attendance record in that game for the second time in his tenure. The team finished with a losing record overall, the first time Arkansas had done that since
2009–10.
