NFL Media Insider Ian Rapoport reported Friday that the $11.3 million franchise number for cornerbacks makes the tag unrealistic for the Dolphins, according to a source with knowledge of the situation.
It appears the Dolphins don't want to hang that high cap number on Grimes if the sides can't come to a contract agreement.
Rapoport's report doesn't mean that Grimes won't stick in South Beach. Grimes easily was a top-10 corner in 2013 by any measurement (Pro Football Focus ranked him their No. 2 player at the position).
At 30 years of age, however, it's likely the Dolphins don't want to give Grimes a long-term contract. The team also might believe that Grimes won't fetch near that $11.3 million tag figure on the open market.
