The Colts defense didn't do anything well last season and you cannot expect much improvement this year. A pass-happy, quarterback-led team generally plays up-tempo and it stresses the defense even more, too. If there is a strength of their unit it lies in safeties LaRon Landry and Antoine Bethea, who get solid value in IDP leagues because the front seven of their 3-4 defense is usually so porous. The Colts did draft a pass-rush outside linebacker in Round 1 (Bjoern Werner), but that should be considered a net-zero with the departure of veteran end Dwight Freeney, who signed with the Chargers. Don't bother with this unit in any fantasy leagues and consider the safeties in IDP formats only late. They are a function of the overall's unit's weakness than their true talent.
