Career
Claphan played on the 1974 and 1975 National Championship teams and was the starting lineman for the Oklahoma Sooners from 1975–1978. At 6' 7" and 295 lbs, Claphan was the largest player on the team. He was selected in the second round of the 1979 NFL Draft (47th overall pick) by the Cleveland Browns but failed to make the roster due to a preseason injury. He was picked up by the San Diego Chargers in 1980.

Claphan played longer in the NFL than any other University of Oklahoma lineman. He was a starting offensive tackle for the San Diego Chargers, protecting the blind side of Hall of Fame quarterback Dan Fouts. He was with the Chargers from 1981 to 1987 until he retired. Claphan, a Cherokee, was inducted into the American Indian Athletic Hall of Fame in 1994.
