One easy move should be releasing defensive end/outside linebacker Quinton Coples, who the Dolphins took a flier on with a waiver claim when the New York Jets cut him in November. Coples didn't record any tackles in the six games he played with the Dolphins. $7.751 million of cap space will be gained if he's gone before his 2016 salary of the same amount becomes fully guaranteed on March 9.
Miami's toughest roster decisions may come with aging veterans Brent Grimes and Cameron Wake. Grimes, who turns 33 over the summer, isn't the cornerback he was as a second-team All-Pro in 2014. It's a $6.5 million cap savings to let him go.
Retaining defensive end Olivier Vernon could cost Wake his roster spot. Vernon came on like gangbusters during the second half of the year after Wake tore his left Achilles when he had seven sacks in seven games played. Vernon's 81 quarterback pressures (combined sacks, quarterback hurries and quarterback hits) were fifth in the NFL according Pro Football Focus. Miami would pick up $8.4 million of cap space from releasing Wake, who is 34.
Vernon reportedly intended to use the maximum value of Cameron Jordan's five-year extension with the Saints, which averages $12 million per year including incentives and contains $33.469 million in guarantees, as a salary floor for a new deal prior to his stellar finish to the season. It will be $15.434 million to franchise Vernon with a $153.4 million salary cap.
Tight end Jordan Cameron was a disappointment. He made $7.5 million while catching 35 passes for 386 yards with three touchdowns. Miami would get $7.5 million of cap room by parting ways with Cameron before his $7.5 million 2016 salary becomes fully guaranteed on the March 10, the second day of the league year.
Wide receiver Greg Jennings, who was buried deep on the depth chart for most of the season, is a luxury with a $5.5 million 2016 cap number. Letting him go yields $4 million of cap space.
