‘Mr. Castro, a Dallas resident who was born in El Paso, often told the story that when he was a little boy, his father told him he should choose a favorite football team. Proud of his Mexican American heritage, he looked for teams whose colors came closest to the red, white and green Mexican flag. The two choices were the Bills and the New England Patriots. Although his father and older brother, both named Jaime, are Dallas Cowboys fans, he picked the Bills.’
