Though much of the Dolphins’ heavy personnel lifting will come on defense, they intend to make a few changes to an offense that finished 26th in yards, 27th in points and 30th in third down efficiency. And those changes start with the offensive line.
Keep in mind that Mike Tannenbaum (with GM Chris Grier) remain in charge of offseason roster procurement. New coach Adam Gase will be consulted, then will have final say on who's on the team in September (though the front office assuredly will have considerable input).
What we’ve been told from inside the building:
### Guard: The Dolphins, who have been somewhat reluctant to spend much at guard in the past, now realize they will need to do what it takes to upgrade at one, if not both, guard spots.
They believe they need better guard play to compete with the formidable defensive tackles in the AFC East, and a bunch of other teams.
The Dolphins believe Dallas Thomas played a bit better than Billy Turner but thought both were inconsistent.
The Dolphins like Baltimore’s Kelechi Osemele --- the best of the impending free agent guards --- but whether they can land him depends on how high bidding goes. Osemele, one of the league’s better guards when healthy, is positioned to land a big contract after a late-season stint at left tackle.
Five other impending free agents who would be upgrades over Thomas or Turner: Denver’s Evan Mathis (rated fourth among guards by Pro Football Focus; Dolphins made him an offer in August); San Francisco’s Alex Boone (rated 39th among guards), Houston’s Brandon Brooks (35th among guards) and two veteran guards who played center this season: Houston’s Ben Jones and St. Louis’ Tim Barnes.
Receiver: Jarvis Landry, DeVante Parker and Kenny Stills will be back, and free agent Rishard Matthews is expected to look for a prominent role elsewhere instead of settling for a potential No. 4 job here. It would be surprising if he returns.
