Defensive end was a very easy position to fill on this team. At right end, Dwight Freeney owns that spot easily. He only played three seasons in this decade with Indy, but he made the Pro Bowl in 2010. He still accumulated 23.5 sacks in those three seasons.
Robert Mathis occupies the other defensive end spot. Mathis played 7 seasons in this decade and made the Pro Bowl in 2012 and 2013, including a First-Team All-Pro selection in 13 when he led the league in sacks with 19.5. Those were the easy choices up front.
Defensive tackle was a little harder. Fili Moala makes the squad after playing five seasons in this decade. He accumulated 81 tackles and 3.5 sacks over that time period. The Colts wouldn’t need him for sacks on this squad though, just for interior run support.
The other defensive tackle position is given to Denico Autry. Autry has only played two seasons with the Colts so far, but he accumulated 69 tackles and 12.5 sacks over that short time. He is a good option to give some interior rush when needed.
While the defensive line wasn’t too hard to pick, the linebackers were a different story. One was an easy selection while the other two were not.
