In 1995, newly appointed Denver Broncos head coach Mike Shanahan drafted running back Terrell Davis in the 6th Round of the 1995 NFL Draft. Entering training camp as the sixth string tailback, Davis was a long shot to make the final roster. That didn't prevent him from doing so, however.
During the team's second preseason game, against the San Fransisco 49ers, Davis impressed the Broncos coaches by laying a huge hit on special teams. Davis would go on to contribute on offense and special teams and was eventually promoted to starting running back for the season's opening game. You know the rest of the story.
Excuse the YouTube video title that says the hit took place in 1998, which is incorrect. Visit GetThemInTheHall.com to learn how you can help get Davis into the Pro Football Hall of Fame.
