The "JC" on Coach Primes shirt stands for Jimmie Callaway, the equipment manager of Florida State University (FSU), where Coach Prime played college football. Callaway was a key figure in the success of the FSU football team and had been with the team for over 30 years, becoming a mentor to many of the players who came through the program, including Deion Sanders. Sanders has worn the initials "JC" throughout his coaching career as a tribute to Callaway, who had a profound impact on his life. Sanders has said that Callaway is "a very important man in my life" and that there is "nobody like My JC". The "JC" initials have become iconic and appear on official merchandise like shirts and hoodies.
