With free agency approaching (March 14), we're analyzing the quarterback position on the Miami Dolphins:
2018 cap hits of top returnees:
Ryan Tannehill -- $19.8 million
Brandon Doughty -- $480,000
Key stat: The Dolphins don't have a quarterback under contract who took a snap in the 2017 regular season. Tannehill, who was replaced by Cutler, will return from a left knee injury. Tannehill has torn the ACL his left knee twice in the past nine months, so the Dolphins will need a reliable backup.
