When 9-11 happened, Pat Tillman quit the NFL. He gave up his million-dollar career, and humbled himself as a U.S. Army [sic] Soldier. And not just a Soldier, but as a U.S. Army Infantryman, a Ranger. Who can ever forget that picture of Tillman, an Army Private, marching in his graduation carrying his platoon guidon, that look of purpose, discipline, Americanism.
