To date, the only black QB to win a Super Bowl is Doug Williams
of the Washington Redskins (MVP of Super Bowl XXII). However,
Williams was not the only black quarterback to play in the
Super Bowl. Donovan McNabb quarterbacked the Eagles in Super Bowl
XXXIX but lost to the Patriots.
Doug Williams - Washington Redskins starting quarterback was
black and won the 1988 super bowl.
Russell Wilson - Seattle Seahawks starting quarterback defeated
the Denver Broncos in Super Bowl XLVIII on February 2nd, 2014.
Doug Williams won Super Bowl XXII (1987-88 season) with the
Washington Redskins to become the first and only black quarterback
to play in and win a Super Bowl (Steve McNair and Donovan McNabb
have played in Super Bowls, but neither won)
