Video: Marlin Briscoe made history at QB

In honor of Black History Month, ESPN looks back at the trailblazing career of Marlin Briscoe, who, with the Denver Broncos in 1968, became the first black quarterback to start in the modern era.

Briscoe went on to play for the Buffalo Bills, Miami Dolphins and New England Patriots. He was a receiver on Miami's undefeated 1972 team.

In October 2008, I wrote a feature on Briscoe's remarkable life -- he has battled a crack-cocaine addiction and lost his Super Bowl rings -- to mark the 40th anniversary of his groundbreaking start.
