Vaughn played in the NBA for the Utah Jazz, Atlanta Hawks, Orlando Magic, Nets, and San Antonio Spurs from 1997 to 2009.

2 point guard in the class of 1993 behind arguably the nation's top player that year, Randy Livingston.

Named a First-Team All-American by nearly every publication on the market, Vaughn rounded off his special season with a selection to participate in the prestigious McDonald's All-American Game where he put on a show, scoring only 6 points but amassing 13 assists (still a McDonald's record), while also thoroughly outplaying the higher-ranked Livingston once again—this time on a national stage (they had both matched up against each other in the All-Star Game of the 1992 Nike Camp), and was named co-MVP with North Carolina's Jerry Stackhouse in the process.

After considering Georgetown, Indiana, UNLV, Arizona and UCLA, Vaughn decided to play for coach Roy Williams at Kansas, continuing, along with fellow recruit and college roommate Scot Pollard, the California pipeline of high school hoopsters to Lawrence, Kansas, started by former standouts Adonis Jordan and Rex Walters, and continuing in later years with Paul Pierce and Eric Chenowith.

[3] In his college career Vaughn became the starting point guard as a freshman after being chosen to replace incumbent starter Calvin Rayford.

Among his first-year highlights were earning the MVP award at the 1993 Pre-Season NIT at Madison Square Garden in New York City and hitting a game-winning three pointer at the overtime buzzer to beat Indiana in an early season game at Allen Fieldhouse.

In 1995, Vaugn was named Arthur Ashe Jr. Sports Scholar by Diverse: Issues In Higher Education.
