Frederick attended St. Joseph High School where he played as tight end. He also practiced basketball. He accepted scholarship to play for the University of New Mexico where he was converted into a defensive tackle.
Frederick was selected by the Dallas Cowboys in the fifth round (137th overall) of the 1977 NFL Draft, to convert him into an offensive lineman. As a rookie, he played on special teams and backed up Ralph Neely at left tackle, who was bothered by an injured knee. He was a part of the Super Bowl XII winning team.
In 1978, he was named the starter at right tackle to replace Pat Donovan who moved to the left side to take the place of the retired Neely. He was relegated into a reserve role after the fifth game after Rayfield Wright reclaimed his old position.
In 1979, he was one of the last cuts in preseason, but was brought back after rookie tackle Richard Grimmett suffered a knee injury one week before the season opener. He contributed on special teams and as a backup.
In 1980, he was the team's only backup tackle and started in the eleventh game against the St. Louis Cardinals in place of an injured Jim Cooper. The next year he remained as a backup tackle. On September 3, 1982, he was waived after being passed on the depth chart by rookie Phil Pozderac.
In 1983, he started 6 games at right tackle for the Chicago Bears. During the Super Bowl run in 1985, he was mostly used as an extra tight end in goal line situations. He was placed on the injured reserve list with a toe injury in 1986. The next year, he failed the physical exam and did not make the team.
