Family background
Isaiah Roby was born on February 3, 1998, in Dixon, Illinois, to parents Danielle and Roderick Roby.[11] He grew up in this small rural community of approximately 15,000 residents, where access to advanced basketball training was limited compared to larger urban areas.[12] Roby has four brothers: Donovan, Ellis, Drew, and Kordae.[11] The family resided in a home constructed through the Habitat for Humanity program, a reflection of their modest circumstances in Dixon.[13] Danielle and Roderick divorced in 2007 after his multiple deployments to the Middle East as a member of the U.S. Army between 2001 and 2007; Danielle then raised the children as a single parent, frequently holding down multiple jobs to provide stability and support Isaiah's budding interest in basketball despite the town's constraints.[14] This dedication included driving him to practices and games, helping to overcome the scarcity of local resources for aspiring athletes.[14] Roby's early exposure to basketball stemmed from family encouragement and involvement in Dixon's community programs, fostering his passion from a young age in an environment where such opportunities were community-driven rather than elite-level.[15]High school career
Isaiah Roby attended Dixon High School in Dixon, Illinois, where he played varsity basketball for four seasons from 2011 to 2015.[11] Joining the team after a 1–28 record the prior year, Roby helped transform the program, leading the Bulldogs to a 76–13 overall mark over his final three seasons.[16] A standout performer, Roby concluded his high school career as the program's second all-time leading scorer with 1,328 points.[11] As a junior, he averaged 12.5 points, 9.8 rebounds, 2.6 steals, and 3.7 blocks per game, earning second-team All-State honors in Class 3A from both the Associated Press and the Chicago Sun-Times.[16] In his senior year, Roby received second-team All-State recognition from the Chicago Sun-Times and received votes in the Illinois Mr. Basketball balloting.[16][17] Roby gained additional exposure through AAU basketball, competing with the Spiece Indy Heat in the Nike Elite Youth Basketball League (EYBL) and the Quad City Elite.[11] Rated a three-star recruit by ESPN and 247Sports, he committed to the University of Nebraska on October 21, 2014, selecting the Cornhuskers over other Midwest programs including Iowa State.[18][19]College career
Freshman and sophomore seasons
Isaiah Roby joined the University of Nebraska men's basketball team as a highly touted recruit from Dixon High School in Illinois, committing to the program in October 2014 under head coach Tim Miles. As a true freshman in the 2016–17 season, Roby faced challenges adjusting to college basketball, including a delayed debut due to a preseason pelvic stress reaction that sidelined him for several weeks.[20] He appeared in 30 games off the bench, averaging 3.1 points, 2.9 rebounds, 0.7 assists, and 0.8 blocks in 15.2 minutes per game, focusing primarily on development and contributing defensively with 25 total blocks, third on the team.[4] [11] During his sophomore year in 2017–18, Roby emerged as a key starter for the Cornhuskers, who finished 22–11 and reached the NCAA Tournament for the first time since 1998 under Miles.[21] He started 14 of 32 games, boosting his production to averages of 8.7 points, 6.3 rebounds, 1.7 assists, and a team-leading 2.0 blocks per game in 24.0 minutes, while shooting an efficient 57% from the field.[4] Roby ranked fourth in the Big Ten Conference in blocks and recorded three double-doubles, all of which came against conference opponents, including a 21-point, eight-rebound effort in a road win over Minnesota.[21] [22] [23] His increased role highlighted his growth as a versatile forward, providing rim protection and rebounding that anchored Nebraska's frontcourt in Big Ten matchups.[21] Throughout his early college years, Roby made academic progress toward a management degree in the College of Business at the University of Nebraska–Lincoln, balancing rigorous coursework with his developing basketball responsibilities.[11] Under Miles' guidance, which emphasized player development and team culture, Roby transitioned from a raw talent to a foundational piece for the Huskers, setting the stage for his breakout junior campaign.[20]Junior season and withdrawal
In his junior season during the 2018–19 campaign, Isaiah Roby emerged as a key contributor for the Nebraska Cornhuskers, starting all 35 games and averaging 11.8 points, 6.9 rebounds, 1.9 assists, and 1.9 blocks per game while shooting 33.3 percent from three-point range.[4] This performance marked a significant improvement from his sophomore year, where he averaged 8.7 points and 6.3 rebounds, showcasing enhanced versatility as a forward with strong defensive presence and efficient scoring inside the arc at 45.4 percent.[4] Roby's contributions were pivotal in helping Nebraska achieve a 19–15 overall record, including a 6–14 mark in Big Ten play.[24] Roby earned All-Big Ten Honorable Mention honors from both the coaches and media panels, recognizing his impact on both ends of the floor as one of the conference's top shot-blockers, ranking fourth in the Big Ten with 66 blocks. He provided leadership during Nebraska's postseason appearance in the National Invitation Tournament (NIT), where the team advanced to the second round after an 80–76 upset win over Butler in the first round; Roby led the Huskers with a career-high 28 points on 9-of-12 shooting in that victory.[25] His role as a starter and vocal presence helped stabilize the team amid injuries and inconsistencies, contributing to one of the program's more competitive seasons in recent years.[26] On March 30, 2019, Roby declared for the 2019 NBA draft while retaining his college eligibility by not hiring an agent, allowing him to gauge professional interest after his breakout year. After participating in the NBA draft combine and workouts, he announced on May 29, 2019, that he would remain in the draft and withdraw from his senior season at Nebraska, hiring an agent to pursue a professional career.[26] This decision capped his three-year college tenure, where he left as the program's active leader in blocks and helped elevate the team's profile heading into the next era.[26]Professional career
Draft and Texas Legends (2019–2020)
Roby was selected by the Detroit Pistons with the 45th overall pick in the second round of the 2019 NBA draft on June 20, 2019.[27] His draft rights were traded to the Dallas Mavericks later that night as part of a multi-team deal involving future second-round picks.[28] On August 7, 2019, Roby signed a four-year rookie-scale contract with the Mavericks worth approximately $6.7 million, with the first-year salary set at $1.5 million.[29] Following training camp, Roby was assigned to the Mavericks' NBA G League affiliate, the Texas Legends, for the 2019–20 season. In nine games with the Legends, he averaged 9.2 points, 7.0 rebounds, and 1.7 assists per game while shooting 50.8 percent from the field.[30] His time in the G League focused on developing his versatility as a 6-foot-8 forward, emphasizing defensive contributions and transition play. On January 24, 2020, the Mavericks traded Roby to the Oklahoma City Thunder in exchange for center Justin Patton and cash considerations.[31] Five days later, on January 29, 2020, Roby made his NBA debut for the Thunder against the Charlotte Hornets, entering in the fourth quarter for two minutes without recording any statistics.[5]Oklahoma City Thunder (2020–2022)
After being acquired by the Oklahoma City Thunder in a January 2020 trade from the Dallas Mavericks, Isaiah Roby secured a spot on the roster under a standard NBA contract as part of his four-year rookie deal, valued at approximately $6.7 million overall.[32][31] Over his two seasons with the Thunder, Roby appeared in 109 regular-season games, providing versatile forward play off the bench and in the starting lineup during the team's rebuilding phase. His contributions included solid rebounding and defensive effort, helping to develop the young core amid a focus on player growth rather than immediate wins.[5] In the 2020–21 season, Roby emerged as a reliable rotation player, appearing in 61 games and starting 34, while averaging 8.7 points, 5.6 rebounds, and 1.8 assists in 23.4 minutes per game, shooting 48.3% from the field.[5] He notched a season-high 19 points on December 29, 2020, against the Orlando Magic, alongside seven rebounds and two blocks. His ability to stretch the floor and switch defensively became assets in head coach Mark Daigneault's system, which emphasized pace and development for emerging talents.[33] During the 2021–22 season, Roby built on his prior year with improved efficiency, playing 45 games and starting 28, averaging 10.1 points, 4.8 rebounds, and 1.6 assists in 21.1 minutes, while shooting a career-best 51.4% from the field and 44.4% from three-point range.[5][34] A standout performance came on March 28, 2022, when he scored a career-high 30 points on 11-of-13 shooting in an overtime victory against the Portland Trail Blazers.[35] Under Daigneault, Roby played a key role in the Thunder's rebuild by offering multi-positional versatility and leadership among the youth, often facilitating plays in transition and protecting the rim.[36] As the 2022 offseason approached, the Thunder exercised their $1.9 million team option on Roby for 2022–23, making his contract non-guaranteed, but ultimately waived him on July 3, 2022, allowing him to enter unrestricted free agency.[37][38] While trade interest had surfaced earlier in discussions about roster flexibility, no deal materialized, ending his tenure in Oklahoma City.[39]San Antonio Spurs (2022–2023)
On July 5, 2022, the San Antonio Spurs claimed Isaiah Roby off waivers from the Oklahoma City Thunder, adding the versatile forward to their roster on a fully guaranteed $1.93 million contract for the 2022–23 season.[40] Roby appeared in 42 games for the Spurs, primarily as a bench player, averaging 11.3 minutes, 4.1 points, and 2.5 rebounds per game while shooting 43.2% from the field.[5] His scoring often came in short bursts, with representative performances including 12 points and five rebounds against the Chicago Bulls on November 20, 2022.[41] Roby's prior experience with the Thunder had honed his multi-positional defensive skills, allowing him to contribute 0.4 steals per game in San Antonio while fitting into Gregg Popovich's emphasis on team defense and spacing.[5] He occasionally guarded multiple positions, using his 6-foot-8 frame and quick hands to disrupt passing lanes, as seen in a December 4, 2022, game where he recorded one steal alongside five rebounds in a loss to the Utah Jazz.[42] This integration helped bolster the Spurs' young frontcourt rotation amid their rebuilding phase. Roby's season was hampered by injuries, notably a right ankle sprain that sidelined him for multiple games leading up to the All-Star break in February 2023.[43] No G League assignments were recorded during his tenure, though the limited minutes reflected the team's depth and his recovery periods. On March 3, 2023, the Spurs waived Roby to make room for another player, concluding his NBA stint with the organization and entering him into free agency.[44]Westchester Knicks (2023–2024)
Following his limited playing time off the bench for the San Antonio Spurs during the 2022–2023 NBA season, Isaiah Roby signed an Exhibit 10 contract with the New York Knicks on October 21, 2023, and was subsequently assigned to their NBA G League affiliate, the Westchester Knicks.[45] In the 2023–2024 G League season, Roby appeared in 17 games for Westchester, starting 15, and averaged 13.6 points, 7.2 rebounds, and 2.5 assists per game while shooting 48.3% from the field.[30] He recorded several strong outings, including a career-high 17 rebounds and 23 points in a March 30, 2024, victory over the Memphis Hustle.[8] Amid efforts to secure another NBA opportunity, including the Exhibit 10 tryout with the Knicks, Roby used his time in Westchester to maintain his conditioning and skills in preparation for potential international options.[46] His G League contract concluded at the end of the season, leading to free agency in the summer of 2024.[32]ratiopharm Ulm (2024–2025)
On July 15, 2024, Isaiah Roby signed a one-year contract with ratiopharm Ulm of the German Basketball Bundesliga (BBL), marking his first professional stint overseas.[47][48] In his debut BBL season, Roby appeared in 15 games, averaging 8.5 points, 4.5 rebounds, and 1.1 assists per contest while contributing on both ends of the floor with his versatile forward play.[49] These numbers highlighted his adaptation to the faster-paced European game, where he often faced physical challenges from established German talents. Roby also participated in the team's EuroCup campaign, helping ratiopharm Ulm advance to the quarterfinals with efficient scoring, including a 48% field goal percentage across his 16 appearances.[50] His contributions included key defensive stops and transition plays, particularly in matchups against top BBL rivals like Bayern Munich and ALBA Berlin, where he delivered double-digit scoring outings.[51] Following the expiration of his contract at the end of the 2024–25 campaign, Roby pursued return opportunities in the United States, leveraging his prior G League All-Star recognition from the previous year.[52]New York Knicks and Westchester Knicks (2025–present)
On October 16, 2025, Isaiah Roby signed an Exhibit 10 contract with the New York Knicks ahead of the preseason. The team waived him later that same day, allowing him to pursue opportunities with their NBA G League affiliate.[10] Following his release, Roby joined the Westchester Knicks for the 2025–26 G League season, where he was named to the opening day roster on November 7, 2025.[2] In the early games, he contributed effectively on both ends of the court, averaging 11.0 points and 5.5 rebounds per game while showcasing improved versatility honed from his overseas stint with ratiopharm Ulm.[53] His performance highlighted his potential as a multi-faceted forward capable of stretching the floor and defending multiple positions. However, Roby's momentum was interrupted by a right knee injury, which sidelined him as of November 9, 2025.[54] He missed the Westchester Knicks' game against the Capital City Go-Go on that date, with his status for upcoming contests uncertain pending further evaluation. As of November 20, 2025, Roby is listed as questionable for games due to the knee injury, with an estimated return around November 12, 2025.[15] At age 27, Roby continues to pursue a more permanent NBA role, leveraging his G League exposure as a pathway back to the league while building on a professional career marked by resilience and adaptability across various teams and leagues.[15]Career statistics
