Sean Smith is set to become an unrestricted free agent in March. If the Dolphins can't agree to a long-term deal with Smith, he might be slapped with the franchise tag, because negotiations for a new contract aren't going smoothly. Ben Volin of The Palm Beach Post cites a source to report the sides are "far apart," with Smith asking for a contract close to the six-year, $43 million pact the Tennessee Titans handed Jason McCourty last summer. The Dolphins aren't about to furnish that type of cash to Smith, according to the source.
