With an offensive line in flux and a defensive line that could be one of the league’s best, the Dolphins are in danger of looking again like a team that opposing quarterbacks fear but opposing defenses can handle.

Rookie defensive end Dion Jordan is being brought along slowly but showed in Sunday’s Hall of Fame Game why he has the potential to live up to his status as the No. 3 overall pick.

The Dolphins already have talented pass rushers in Cameron Wake and Olivier Vernon, and unheralded second-year player Derrick Shelby stepped up Sunday in the 24-20 loss to Dallas.

The same can’t be said for Miami’s offensive line. Left tackle Jonathan Martin, perhaps the most scrutinized Dolphins player coming into the preseason, had mixed results in limited action. Martin, along with the other first-teamers, appeared in only a handful of first-quarter drives.

Martin looked solid in run blocking but didn’t stand out in pass protection. Ryan Tannehill was pressured on a couple of plays, although one was a blown screen pass.

“I think I played really well,” Martin said. “There’s always work to do. I was trying to play confident and just get my body ready for the season.”

Tannehill also praised Martin, saying, “Jonathan’s been great.”

But if he struggles or gets hurt, the Dolphins could have problems.
