This is just as rare as a team going undefeated. Broncos kick returner Trindon Holliday started the year with the Houston Texans, and after their 5-0 start, he was cut. Holliday was then picked up by the Denver Broncos, and the Broncos have won 11 straight. Holliday currently stands at 16-0 on the year, and will look to add to that win total in the playoffs. No NFL team has ever gone 19-0 and Trindon Holliday could be the first player ever to do so if the Broncos can win the Super Bowl.
