He accepted a football scholarship from the University of Houston. As a freshman he played at tight end and defensive end. He was injured during most of his sophomore (knee) and junior (shoulder) seasons.
Brown was selected by the Dallas Cowboys in the fourth round (108th overall) of the 1977 NFL draft, who saw him as an above average athlete and wanted to play him at outside linebacker. As a rookie, he was considered the fastest defensive player on the team and also set the rookie power clean lift record of 315 pounds.[2]
In 1979, Brown was slowed by a groin injury. In 1980, he had a chance to earn the starting strongside linebacker job after Thomas "Hollywood" Henderson was waived, but was passed over by Mike Hegman.[3] Hegman dislocated his elbow in the wild card playoff game against the Los Angeles Rams, which gave Brown a chance to start in the next two playoff games. He was one of the core special teams players during his first four seasons.
In 1981, Hegman fractured his arm in the season opener, giving Brown the chance to start six games at strongside linebacker.
After experiencing recurring neck problems and visiting with doctors,[4] Brown was subsequently diagnosed with a narrow spinal column condition (cervical spinal stenosis), which forced him to announce his early retirement on July 11, 1983.[5] He was replaced in the starting lineup by Anthony Dickerson.
