The Indianapolis Colts' secondary might be the best unit on the defense.
Led by stud cornerback Vontae Davis and 2014 Pro Bowler Mike Adams, the Colts finished 2014 ranked 10th against the pass in Football Outsiders' defense-adjusted value over average ranking, the team's best ranking since safety Bob Sanders won the NFL Defensive Player of the Year Award in 2007.
That success against the pass came despite a poor pass rush that depended on a blitz-heavy game plan to get the quarterback, leaving the secondary with little help most of the time. It was especially impressive in games against Baltimore, Cincinnati and Denver last season, although there were a few stinkers thrown in (Pittsburgh, Dallas).
