The Miami Dolphins continued the free agent signing bonanza Friday by securing the services of wide receiver Brandon Gibson. “We are happy that Brandon is joining the team,” said Dolphins General Manager Jeff Ireland. “Coupled with the earlier addition today of Dustin Keller, we feel that we have added some very good pieces to our passing game.” Ireland has gone all-in on the free agents this week and has signed wide receiver Mike Wallace, tight end Dustin Keller, linebackers Dannell Ellerbe and Phillip Wheeler, and the aforementioned Gibson.
