Tom Flores is one of two people to win the Super Bowl as a player (unfortunately with KC), assistant (under Madden) and coach (twice). (edit) Ditka was the other, following Flores on all three fronts. (/edit) If people ask about Dungy, he never won as an assistant.
Although disputed, he is the first Hispanic coach...
Who was the first hispanic head coach in the NFL
Mr. Davis also hired the first black coach of the modern era (Art Shell) and first female CEO (Amy Trask).
