Defensive Backs
Miami has a huge void to fill in the secondary, if the team plans to compete with the rest of the AFC in 2016. The Dolphins' pass defense ranked 21st in the league last season, allowing over 250 yards per game through the air. Outside of Reshad Jones and Brent Grimes, Miami is lacking at both the safety and cornerback positions. The Dolphins have an important decision to make on Grimes, who is scheduled to make $8 million in 2016. Miami could choose to cut or restructure the 31 year old cornerback, a decision that could directly effect the Dolphins interest this off-season.
At safety, Reshad Jones had the best season of his career in 2015, recording 135 tackles, 2 sacks and 5 interceptions. The Dolphins will look to add a free safety to partner with the Pro Bowler, otherwise relying on new defensive coordinator Vance Joseph to get the most out of Walt Aikens and Michael Thomas.
