It is no secret the Miami Dolphins offensive line hasn’t been the greatest of units the past few seasons. At the end of last year, Pro Football Focus ranked the Dolphins offensive line the 30th best in the league.

Now, entering the 2017 season, PFF ranks the Dolphins offensive line a tad better than at the end of last year as the publication, ranking them No. 26.

Here’s what writer Michael Renner said about ranking the Dolphins offensive line:

After finishing with the league’s two lowest-graded guards in 2015, Laremy Tunsil brought some semblance of competency to the position last year. They could very well be back to that 2015 level again though, as Tunsil moves to left tackle, where he is an unknown. Right guard Jermon Bushrod finished as the fourth-lowest-graded tackle in the league last year, while projected left guard Anthony Steen wasn’t much better in 408 snaps last year.

Tunsil did fill in for Branden Albert a short time at left tackle last season. Gase and the Dolphins coaching staff thought enough of Tunsil’s play to trade Albert in the offseason.

Renner is right about the guard position as Bushrod is a question mark, despite Gase saying he was the team’s second-highest rated offensive lineman last season. Ted Larsen will likely be the starter at left guard, but Steen could potentially challenge him.

Miami’s offensive line didn’t play terribly last season as it gave up 30 sacks for 10th-least in the league. Its offensive line also paved the way for Jay Ajayi to have a Pro Bowl season at running back. Although they’re some question marks, there were also some positives on the Dolphins offensive line last season.
