They are basically done with free agency and focused on the draft. With that said, I still think there will be at least one more signing. Not likely a major move, but I think there is still a chance they ink another free agent.
With that said, one thing we need to keep in mind is that team's can only take 80 players into camp. Miami currently has 66 players on the roster with only room for 14 more. If no trades are made and Miami uses all their draft picks, that will take up another 8 slots leaving them with 6 empty slots. So the question is, are all 6 spots going to go to UDFA?
