Ralph Waldo Van Dyke III was born on January 19, 1964, at St. James Hospital in Chicago Heights, Illinois, to Ralph Waldo Van Dyke, Jr. and Mattie Lou Van Dyke.[3][4]
Van Dyke was a redshirt during his freshman year at Southern Illinois in 1982. He became a starter for the team by the fifth game of the 1983 season, and was noted as an "extremely aggressive" hard worker by coach Rod Sherrill in 1983, shortly before the Salukis won the NCAA Division I-AA championship.[6]
After a below-average performance at the NFL Scouting Combine,[8] Van Dyke was drafted by the Atlanta Falcons in the fourth round of the 1987 NFL draft, with the 97th pick overall.[9] He signed with the team in late July 1987,[10] but was waived roughly a month later on August 31.[11]
During the 1987 NFL strike, Van Dyke signed with the Cleveland Browns as a replacement player, starting at offensive tackle in the team's Week 4 and Week 5 games.[12] The strike ended after Week 6 and Van Dyke was released by the Browns.
Van Dyke signed with the Phoenix Cardinals on March 31, 1988, in the midst of the team's relocation from St. Louis, Missouri to Phoenix, Arizona. He suffered a sprain to his knee in July 1988 during the team's training camp in Flagstaff, requiring him to be sent south to Phoenix for treatment.[13] He left the team's camp on July 28, 1988.[11]
