Joe wasn’t going anywhere by ‘73. Even turned down pro offers.
And Schwartzwalder was a genuine WWII hero. From Wiki link posted above.
As a captain in the 82nd Airborne (CO of Company G of the 507th), Schwartzwalder earned a distinction during the invasion of Normandy and battles that followed in the last days of the war. He played key roles in the capture of the La Fière Causeway and Sainte-Mère-Église, crucial points of entry into France during the D-Day invasion. By the time the 507th reached the battle for Hill 95, they had suffered more than 65% casualties. Schwartzwalder continued his campaign all the way into Germany and acted as military governor of the town of Essen for a period of six months. He was awarded a Silver Star, a Bronze Star, a Purple Heart, four battle stars, Presidential Unit Citation and was promoted to the rank of Major for his actions during the invasion. When he was personally decorated by General Matthew Ridgway, the General said "Ben, I never expected to see you here to receive this award."
Even as a paratrooper, Schwartzwalder remained focused on his football career. He organized an athletic league from among the soldiers being assembled in England in preparation for D-Day in order to keep the troops motivated and fit. He coached the 507th PIR football team, leading them through a ten-game season in which the 507th was never defeated and never even scored upon.
