Davis was the first African-American to win the Heisman Trophy in 1961, while playing running back for Syracuse. He looked to be headed into a promising NFL career; he was taken No. 1 in the draft by the Redskins, and was later traded to the Browns. Sadly, Davis was diagnosed with leukemia shortly after being drafted in 1962, and never played in an NFL game.
