With the addition of Byron Jones, head coach Brian Flores has a tandem of cornerbacks that allow the Dolphins to play a lot of man coverage on the outside.

Flores can use him as a matchup piece on the defensive side of the football, tasking him with man coverage on tight ends or even wide receivers, or using him to provide help over the top.
