The Dolphins ultimately never inked a big-name left tackle in free agency, but Miami did sign dyed-in-the-wool right-sider Tyson Clabo. His arrival means that second-year offensive lineman Jonathan Martin will take over for the departed Jake Long at left tackle, where Martin thrived at Stanford. Following an offseason of frantic free-agent signings, the success of Miami's rebuilt offense arguably boils down how Martin adjusts. "I'm excited. It's a position I want to play, obviously," he told the team's official site. "I'm excited for the challenge, I'm excited for the opportunity so I'm going to try to make the most of it during these OTAs and do whatever I can to help this team win." Martin struggled mightily as a rookie on the right side. Teammate: Jonathan Martin 'more fluid' at left tackle - NFL.com
