Indianapolis Colts: 15 best free agent acquisitions of all-time

Darius Butler might be one of the most underrated defensive signings the Colts have ever made. The guy was on two teams in three years and seemed destined to be an NFL wash out. Then, he came to Indianapolis and resurrected his career.

Butler was signed in 2012 and played a solid six years with the Colts. He was able to play a multitude of positions, though his best position was corner. Although Butler rarely started, he was a consistent player that the Colts could put out there on any given play.

Butler had four interceptions in each of his first two years with the Colts, and three of those he took back for touchdowns. Over the course of his six years in Indianapolis, he had a total of 12 picks and nine forced fumbles. He was a big play waiting to happen on the defensive side of the ball.

Toward the end of his career, the Colts tried moving Butler to safety. He wasn’t as effective in that role, as he didn’t record a single pick. Ultimately, the Colts decided to move on from Butler in 2017. He hasn’t played in the league since.

Butler played with the Colts at the end of his career, much like the next guy on this list. And like Butler, he was also a big play waiting to happen on defense.
