Trindon Holliday's perfect season

The 1972 Miami Dolphins may have to worry about Trindon Holliday.

The Denver Broncos' return man went 16-0 in the regular season.

He was with the Houston Texans for the first five games of the season. Houston was 5-0 in those games, Holliday was cut and he was claimed by the Broncos.

The Broncos have won 11 straight games after going 2-3. No NFL team has ever gone 19-0, but Holiday is three games from achieving it.
