Year after year, the Miami Dolphins make free-agency splash after free-agency splash.
The theory: One or two key signings will put the team over the top, filling a need and bringing the Dolphins closer to a "complete" team.
The results: a lot of guaranteed money for players who haven't produced anything better than the .500 records we've come to expect from the Dolphins in the past half-decade.
The logic behind signing defensive tackle Ndamukong Suh was sound. The Dolphins have struggled to stop the run over the past two seasons while anchored by a defensive line comprised mainly of pass-rushing specialists.
