Known for his outside shooting and remarkable leaping ability, Delph was a member of the University of Arkansas Razorbacks NCAA Final Four team in 1978. Along with Sidney Moncrief and Ron Brewer, he was labeled as one of the "Triplets", a trio of Arkansas-born, similarly-sized players who led Arkansas basketball through a tremendous resurgence after years of mediocre play.
Following his college career, Delph was drafted in the 3rd round of the 1978 NBA Draft by the Buffalo Braves. Unlike his fellow Triplets, Delph never played in the NBA, despite several attempts. He continued playing amateur basketball with the Athletes in Action team, a religiously-oriented team.
Delph was inducted into the Arkansas Sports Hall of Fame in 1998.
