Neal is horrible in coverage. I get his value on ST but with the rules making the return game lesser and lesser (see KO fair catch rule) I don't think ST coverage guys should stick around more then 4 years if don't contribute elsewhere.
Miami has Bradley Chubb and not sure what picks have left. Toss in they likely gonna have to pay Tua after this year. I'm thinking it be Tennessee or Jacksonville if they could free up cap space.
