After Garnett was drafted in 1995, Fields, in his senior year, led his squad to an 11–1 record in the Chicago Public League with per-game averages of 32.4 points, 12.2 rebounds, 5.1 assists, 4.5 blocks, 4 steals, and 4.5 dunks a game.
He became a consensus First Team All American (Parade, USA Today, McDonald's), putting him in the company of future NBA players Mike Bibby, Jermaine O'Neal, Tim Thomas, and Kobe Bryant.
After being recruited by Joey Meyer, Fields signed a letter of intent at DePaul University in his hometown but was later ruled academically ineligible and denied admission.
In November 2008, Fields returned to play basketball in the CBA for the Minot SkyRockets, signing as the starting shooting guard.
[3] Ronnie Fields was known to be a strong scorer near the basket, but although he had improved other parts of the game over time, such as passing, court vision, and defence, he continued to struggle with outside shooting.
[7] As of 2023, he is the founder and coach of Ronnie Fields Elite, which organizes basketball programs for middle and high school students.
He is also one of two guests on Episode 22 of KG Certified, entitled The Farragut Reunion W/ Ronnie Fields & Coach Wolf Nelson (2022), hosted by Kevin Garnett.
