Doug Williams coaches his son, D.J.

Before Doug Williams made history as the first black quarterback to win a Super Bowl, he was a star at Grambling University.

After his pro career ended, Williams went on to coach his alma mater - and then left Grambling to work as an executive in pro football.

Two years ago, Doug Williams, III - D.J. for short - signed on to play quarterback at Grambling, following in his dad's footsteps.

Doug insists he treats D.J. just as he would any other player. Although the dynamic can get dicey.

D.J. wasn't yet born when Doug made history 25 years ago.
