NFL teams can begin using the franchise tag on Feb. 17, which is just one week away.
Grimes was arguably Miami’s best defensive player last season. He tied for the team lead with four interceptions and was responsible for guarding the opponent’s No. 1 receivers. Grimes said after the season this was the best year of his career.
The Dolphins are short on proven cornerbacks and cannot afford to lose Grimes, who is scheduled to become an unrestricted free agent in March. A top-level cornerback could command $7 million per year or more on the open market. The tag would also allow both sides more time to negotiate a long-term extension.
