O'Bannon originally planned to attend the University of Nevada, Las Vegas (UNLV), but he did not sign a letter of intent with the university at the suggestion of UNLV head coach Jerry Tarkanian. However, when UNLV's men's basketball program was placed on probation due to recruiting improprieties, O'Bannon rescinded his commitment and instead attended UCLA.[5]
Leading up to the 1995 NBA draft, O'Bannon hoped to be drafted by a team on the west coast. Selected ninth overall by the New Jersey Nets, he signed a three-year, $3.9 million contract. However, he became homesick.[12] In his two professional seasons, he was unable to find a place in the NBA, being too lean to play down low and not quick enough with his rebuilt knees to guard the perimeter.[5] His knee also started to break down.[12] He averaged 6.2 and 4.2 points per game respectively with the Nets and was traded to the Dallas Mavericks later in his second and final NBA season, where he had even less of an impact. In September 1997 he was traded along with Derek Harper to the Orlando Magic for Dennis Scott, and was waived by the Magic afterwards. "It wasn't injury, it was confidence," O'Bannon said about his NBA career. "I missed shots, got pulled from games, it affected my defense, and I lost all my confidence."[13] Former Nets teammate Armon Gilliam said, "He's a guy who didn't find his niche in the NBA. He wasn't in the right situation to grow and develop. He never got the opportunity to prove what he could do."[5]
Career in Europe and the ABA
After his NBA career, O'Bannon played professional basketball seven years overseas in Italy, Spain, Greece, Argentina and Poland (in Anwil Włocławek, Polonia Warsaw and Astoria Bydgoszcz).[5] He also played one year for the startup American Basketball Association (ABA) with the Los Angeles Stars.[12] After the NBA, he only had one-year contracts and never made more than $400,000 in a season.[12] He decided to retire at age 32 after undergoing arthroscopic knee surgery.[citation needed] When he made his decision, he was in the process of trying out for a team in China but realized he had no more motivation to play the game.[5] Furthermore, the people holding the tryouts had never even heard of him.[13]
In his professional career, O'Bannon said he "played for 12 different teams in at least six countries and for 15 different coaches."[14]
Subsequent career
As of 2009, O'Bannon was employed as a marketing director for a Las Vegas auto dealership.[15] In 2006, while employed as a salesman at the dealership, O'Bannon told the Los Angeles Times, "People see me and remember me and I'm proud to tell them—'No, I don't play. No, I don't coach. Yes, I sell cars.'"[13] By 2020, he had become a probation officer in Las Vegas.[16]
O'Bannon was the lead plaintiff in O'Bannon v. NCAA, an antitrustclass action lawsuit filed against the National Collegiate Athletic Association (NCAA) on behalf of its Division I football and men's basketball players over the organization's use for commercial purposes of the images of its former student athletes. The suit argued that upon graduation, a former student athlete should become entitled to financial compensation for future commercial uses of his or her image by the NCAA.[18][19] In January 2011, Oscar Robertson, considered one of the greatest basketball players of all-time, joined O'Bannon in the class action suit.[20] On August 8, 2014, Judge Claudia Wilken ruled that the NCAA's long-held practice of barring payments to athletes violated anti-trust laws.[21]
In March 2015, O'Bannon appeared in a faux commercial on Last Week Tonight with John Oliver on HBO that criticized the NCAA's payment practices regarding student athletes. With March Madness approaching, the commercial featured a fake video game named March Sadness 2015 that mocked the experiences of college basketball players in relation to the NCAA. "This game is every bit as fucked up as the real thing,” stated O'Bannon in the segment.[22] In 2018, he published a book about his fight with the NCAA, Court Justice: The Inside Story of My Battle Against the NCAA.[2] O'Bannon supported the Fair Pay to Play Act, a California law that allows college athletes to receive endorsement deals.[16]
O'Bannon attended UNLV to continue earning his bachelor's degree.[6] In the summer of 2011, O'Bannon returned to UCLA to complete his studies, and he graduated in the fall that year with a degree in history.[24][25]
