Cited by future Hall of Fame coach Doug Ethridge as the best blocker he’d ever seen, the two-way star earned second-team all-state honors at center as a junior (while also playing defensive tackle), and was first-team all-state at end as a senior in 1968. He also made Texas Football’s preseason Super Team that year at center. During his two varsity seasons, Foster made an all-state team at four different positions. The 6-4, 240-pound blue-chipper signed with Oklahoma, where he opened holes for THSFHOF members Joe Washington, Greg Pruitt, Joe Wylie & Jack Mildren. Foster also earned all-Big 8 and all-America honors (Family Weekly, Walter Camp) at offensive tackle. He played with the World Football League’s Jacksonville Sharks (1974) and Birmingham Vulcans (1975), and for the Canadian Football League’s Saskatchewan Roughriders in 1975.
