Reggie had to overcome hip deformities as a youth growing up to finish an All-CIF outstanding high school shooting career at Riverside Poly HS, which led to a UCLA basketball scholarship. He became the first Pac-10 Post-Season Tournament MVP and an All-American as a senior after being the NIT MVP as a junior in leading the Bruins back to national prominence with the 1985 crown. He was the first-round NBA draft pick of the Indiana Pacers (11th overall) where he spent his entire 18-year pro career and retired as the all-time NBA three-point leader and led the league in free throw percentage five times. He was a five-time all-star and led Indiana once to the NBA finals.

The 6-7 Miller won an Olympic Gold Medal in 1996 in Atlanta (joining Cheryl Miller as the first brother-sister basketball gold medal winners). He was inducted into the Naismith Basketball Hall of Fame as well as the Pac-10 Hall of Honor and UCLA Athletics Hall of Fame. He is also in the Riverside Sports Hall of Fame. His number 31 jersey has been retired by both UCLA and Indiana. He currently is an NBA and NCAA playoff broadcaster for Turner Sports and the TNT network.
