After finishing third in what was a poor AFC South division in 2016, the Colts head into the offseason with as many as six defensive regulars up for free agency. The good news: 1) the Colts’ defense was already one of the worst units in the league, and 2) there’s plenty of cap room for the team to acquire talent, especially in the front-seven. While Andrew Luck (92.4 grade in 2016 – fourth among quarterbacks) can do quite a bit to carry an offense single-handedly, don’t rule out the Colts tapping into a good group of free agent guards, or even going after a player like Martellus Bennett, as well, in free agency.
