Indianapolis Colts’ general manager Ryan Grigson addressed many needs via free agency but his job is far from done. On the defensive side of the ball the Colts lost a few bodies but wasted no time to sign new players: defensive lineman Kendall Langford and pass rusher Trent Cole are the two newest members of the 2015 Colts’ defense, alongside cornerback Darius Butler and safety Mike Adams who re-signed with the team.

Bringing Mike Adams back was a priority of this offseason for the Colts as they lost both Sergio Brown (now with the Jacksonville Jaguars) and LaRon Landry (still a free agent). While the latter has been a major disappointment, Brown was a solid player in 2014 although he missed most of the playoffs and left the Colts with a hole at safety.

How can the Indianapolis Colts fill that spot next to Mike Adams?

The in-house replacement could be Colt Anderson, an exceptional special teamer that played only 7.1% of the defensive snaps last season, per Pro Football Focus (subscription required). Is he ready to take on a bigger role and be a starter in 2015?

This is something only head coach Chuck Pagano and the rest of the coaching staff know for sure. Meanwhile they could be looking at other options, in particular at draft prospects since the free agent market has significantly dried out.
