Frei himself was known to be conservative, but his philosophy was that especially because he had flown in combat when younger than many of his players and had been forced to grow up fast; he wasn't going to try to control his young players' lives, dictate their hairstyles, or attempt to censor their political views away from the field. He steadfastly refused to call his players "kids," and some made fun of or never understood his unvarying references to them as "young men." His positive impact on his players during turbulent times was long-lasting.
