When he was young and watched his father's Giants practice and play from the sidelines, the New York players called him with a nickname "the Duke" because of the royal position in Great Britain, the Duke of Wellington. The NFL admired the innovations of Wellington so much that in 1941, they nicknamed the version of the Wilson Game ball " 'the Duke" in his honor.

Under Wellington's leadership the G-men won 6 NFL Titles, which included two Super Bowl wins.
