Chris Ballard said during Monday's pre-Draft press conference that he felt like the players in the "15 to 70" range were all around the same level, so it's no surprise he decided to trade out of the #26 pick:
The Colts have three second round selections (plus next year's Redskins' #2 pick) in tow, but could add even more if they trade out of the #34 spot. Ian Rapoport said they could be interested in trading down again:
As Rapoport says, a team could want to trade up to get one of the top O-Linemen that fell, a wide receiver like DK Metcalf, or perhaps even one of the Day 2 quarterbacks like Missouri's Drew Lock.
Regardless, the Colts are in a great spot to either pick second tonight or add to their draft capital bounty in 2019 and 2020.
