Since Miami Dolphins head coach Adam Gase arrived in 2016, the team has emphasized improving the secondary. Despite having a former Pro Bowl safety, Pro Football Focus doesn’t think highly of the Dolphins’ secondary heading into training camp.

In the latest PFF article ranking all 32 NFL secondaries, the Dolphins were placed at No. 19.

Here’s the explanation the Pro Football Focus:.

On a defense that otherwise appears to be loaded, the secondary is a relative weak spot for the Dolphins. CB Byron Maxwell will look to duplicate a strong 2016 campaign that saw him yield just two receptions longer than 20 yards in 13 games played, and having S Reshad Jones back healthy should provide a much-needed boost to the unit. Elsewhere, youth will be key, as Xavien Howard will look to improve upon the 94.3 passer rating when targeted he posted during his rookie campaign of 2016, and third round pick Cordrea Tankersley should also have a significant role in 2017.

During the offseason program in May, safety Reshad Jones said folks attempting to put a ranking on the team’s secondary should pump their breaks.

“It’s early to put any rankings or anything like that, but I do think we have a good group,” Jones said. “We have a lot of good pieces in Nate Allen we added and T.J. (McDonald). ‘X’ (Xavien Howard) is playing good and like I said, Tony Lippett is playing probably the best ball he’s been playing. I think we can be special. We’ve got the ball rolling in the right direction, we’ve just got to continue to put the work in and make it happen.”

Last season, Miami ranked 15th against the pass as it gave up an average of 242.2 passing yards per game. With the team getting a healthy Jones Maxwell and Howard back, it should prove better than PFF’s ranking.
