Nearly 20 years ago, one of the most significant rule changes in NBA history occurred when the league’s collective bargaining agreement prohibited high school seniors from entering the NBA Draft. The rule stated that players must be at least 19 years old and at least a year removed from high school graduation to enter the draft.

Fast-forward to today, and the term “one-and-done” has become prevalent in sports, referencing players who played only one college season before moving to the NBA. Notable one-and-done stars over the past two decades include Carmelo Anthony, Anthony Davis, Zion Williamson, and Cooper Flagg, a standout from Duke.

But what if the one-and-done rule had always existed? Our team at FOX Sports delved into research to project where top high school-to-NBA players might have ended up had they been required to play college basketball.

10. Tyson Chandler: UCLA

Chandler was a prep superstar at Dominguez High School in Compton, CA. He was named a Parade All-American and participated in the McDonald’s All-American Game. As a UCLA fan, he considered several schools but skipped college to enter the 2001 NBA Draft instead.

9. Jermaine O’Neal: South Carolina

Born in Columbia, SC, O’Neal aimed for the Gamecocks before entering the NBA Draft after a stellar senior year. In a recent interview, his son mentioned that his father was considering South Carolina before making the jump.

8. Shawn Kemp: Kentucky

Kemp starred at Concord High School in Indiana but chose to commit to Kentucky. Issues with eligibility led him to eventually declare for the NBA Draft.

7. Amar’e Stoudemire: Memphis

Stoudemire played at five different high schools but finished at Cypress Creek High School. He verbally committed to Memphis but later chose to go straight to the NBA.

6. Tracy McGrady: Kentucky

McGrady’s high school journey led him to Mount Zion Christian Academy in North Carolina. He frequently referred to Kentucky as his “adopted school” during his NBA career.

5. Dwight Howard: North Carolina

Imagine adding Howard to the 2005 North Carolina Tar Heels team. Although Howard jumped from high school to the NBA, it’s speculated he would have attended UNC.

4. Moses Malone: Maryland

Malone signed a letter of intent for Maryland but jumped to the pros after being picked by the Utah Stars.

3. Kevin Garnett: Maryland

The debate continues on where Garnett would have played if he hadn’t entered the NBA straight from Farragut Academy. He once stated he would have chosen Maryland over Michigan.

2. Kobe Bryant: Duke

Acknowledged as one of the greatest, Bryant was heavily recruited by Duke. He stated that Coach K was particularly interested in him, although he ultimately headed straight to the NBA.

1. LeBron James: Ohio State

If LeBron had not bypassed college, indications suggest he would have attended Ohio State, emphasizing the allure of playing in his hometown.
