The Colts are just going to keep building through the draft

There was a lot made of the Colts' 2018 season and their position as the off season approached. They were a team on the upswing, and they were in a place of great financial flexibility, so some massive moves were expected, with holes on defense and a wide receiving corps that was very shallow, as well as a widely stated need for a running back.
The free agency glut came and went, and the Colts came away with.... Devin Funchess. Later, the Colts went out and added Justin Houston and Spencer Ware, but that was long after the premium names were already off the board.
The Colts then went to the draft, and the general consensus was that they crushed it. They traded out of the first round, and had three picks in the 2nd round, which they used to fill three pressing needs: Rock Ya-Sin, a cornerback, Ben Benogu, a linebacker and Parris Campbell, a wide receiver. This is the second year in a row that the Colts have potentially done extremely well with the draft.
That's a great thing to have in their back pocket. As they continue to develop internally, with young players breaking out, they will be able to either retain players in the long term, or in the short term, add that final component to a potential championship team.
Which, uh... I guess is what the situation was this year. To me, that signifies that they could get more out of the prospects they are adding than the entirety of the free agent pool, which is incredibly arrogant. Of course, Chris Ballard, the GM, is yet to be proven wrong in his Indianapolis tenure. We can call it confidence, since Ballard has already started to turn the team around using similar methods in previous off seasons.
The Colts could have added a bunch of free agents to round out the roster. They didn't. They could probably do it again next year. They probably won't. That doesn't seem to be how this organization wants to operate.
