Okoro was born Jan. 26, 2001 in Atlanta, Georgia to Nigerian parents, Godwin and Gloria Okoro. Isaac was raised close to downtown Atlanta. He has three siblings: Michael, Rachel and Ashley. Okoro began playing basketball in his local church league. While around seven years old, he was trained by AAU coach Omar Cooper. Okoro played high school ball at McEachern High School in Powder Springs, Georgia, and graduated with honors. As a sophomore, he led the team to the regional championship while averaging 22.5 points per game. Later, as a senior, he averaged 19.7 points, 10.6 rebounds, 3.2 assists and 2.7 steals per game and led McEachern to titles at the City of Palms Classic and the Tournament of Champions. The team finished 32-0. Okoro had his jersey retired by the school in 2019. At college, he went to Auburn, where he studied business and was named Second Team All-SEC as a freshman. After his freshman season, he declared himself eligible for the 2020 NBA Draft. Fans can follow the forward on Twitter @isaacokoro303. Okoro needed just one season with Auburn to prove to scouts he was NBA ready despite the fact neither ESPN or Rivals had him ranked in their top-25. The 6-6 wing debuted Nov. 5 against Georgia Southern, scoring 12 points and starting a streak of six consecutive games in double figures. Okoro's collegiate career high came in SEC play, as he put up 23 points in a 83-79 victory over Vanderbilt on Jan. 8. He finished the year with averages of 12.9 points and 4.4 rebounds, but Okoro's defensive contributions were also of major note, as he went on to earn first-team SEC All-Defense honors. He also made the SEC All-Freshman team and second team all-SEC that year. Auburn had been in line for a bid in the NCAA Tournament, but it was canceled due to the coronavirus pandemic and Okoro made clear his intentions to explore the NBA Draft on March 20, later making his decision official May 9.
