Cornerback
There’s really only one cornerback the Colts need to target in free agency, and there is an argument that he should be their top priority on the market. That would Byron Jones of the Dallas Cowboys.
He’s uber-athletic and has the versatility to play on the outside and as a safety. He has a familiarity working in Matt Eberflus’ defensive scheme from their time in Dallas. He doesn’t rack up the interceptions, but his coverage is tight, and he would give the Colts an immediate upgrade over Pierre Desir.
The other options like Chris Harris Jr. and Logan Ryan aren’t all that appealing, but Jones should be among the top priorities in the market.
