Dolphins' positional breakdown: OL

The Miami Dolphins still do not yet have a general manager. But that new hire will have plenty of decisions to make in shaping the roster.

We continue to examine each position. Next up, we look at the offensive line.

OL under contract in 2014: C Mike Pouncey, G Nate Garner, OT Jonathan Martin, G Sam Brenner, G/T Dallas Thomas

Free agents: G John Jerry, OT Tyson Clabo, OT Bryant McKinnie, G Richie Incognito, OT Will Yeatman, G Danny Watkins

Analysis: The Dolphins allowed a franchise-record 58 quarterback sacks and were 26th in rushing. Miami’s offensive line is in major need of a makeover. This much-maligned group was a primary reason the Dolphins were inconsistent offensively. Miami couldn’t establish an identity running or passing because the team was consistently dominated in the trenches. In addition, the bullying scandal involving Incognito and Martin certainly didn’t help matters. This is the ideal time to make major changes. Key free agents such as Incognito, Jerry, Clabo and McKinnie all came off Miami’s books after the season and most, if not all, are not coming back. Martin’s future also is extremely shaky in Miami. The Dolphins are expected to explore trade options or release the former second-round pick.
