The Miami Dolphins can sign any player right now and it does not effect their compensatory formula. They need a veteran cornerback and according to Barry Jackson of the Miami Herald, the Dolphins have talked about a couple veteran cornerbacks over the past couple days.
The Dolphins internally have discussed unsigned veteran corners Leon Hall and Antonio Cromartie. The only 2015 full-time cornerback starters, below the age of 35, that are still available are Cromartie and Arizona’s Jerraud Powers (Miami has not pursued Powers to this point).
Cromartie has said he wants to play football in 2016, and Leon Hall has been on several visits. This could be a great signing for the Dolphins, who lost Brent Grimes.
