6. Don Streinbrunner
For many years, Don Streinbrunner was not recognized as the first of two professional footballers to die in Vietnam. The Cleveland Browns offensive tackle played one full season, helping his side to the 1953 NFL Championship final. He opted to enter the Air Force the following year, to fulfill his military requirement.
Steinbrunner chose to stay in the Air Force and leave the professional game behind because of a knee injury. He’d take part in the Vietnam war and lost his life when the Viet Cong shot him down on a defoliation mission as he sprayed Agent Orange. All five crewmembers on his bomber lost their lives. Finally, the Browns honored him in 2004.
