After the upcoming weekend passes and Super Bowl XLVII becomes nothing more than a memory, the offseason will begin in full. The mad dash of free agency will become the highlight of discussions, even though it's still roughly another month away.
The Miami Dolphins have approximately $46 million in cap space. This has led plenty of people to believe that the Dolphins will be big players in free agency, despite somewhat disputing remarks from owner Stephen Ross.
Nevertheless, Miami is likely to make a few moves in free agency (especially if GM Jeff Ireland wants to keep his job). With holes at wide receiver, cornerback and offensive line, the Dolphins will certainly look for improvements in the horde of available veterans.
