Free Agency is still a way off and this list will change, but I thought it would be a good to get a discussion going on which Free Agents we should or could potentially target. I tried not to include anyone older than 30. I will say that this is far from a complete list, these would be you higher-rated FAs so they will cost a little more money (some a considerable amount of money).

I won't name names, but I doubt Miami will sign ANY FA top 1 or 2 at his position. Now, that's just a gut feel, no evidence, but I think Miami will be smart with it's cap and getting, say, the 4th best for far less $ will still be an amazing upgrade at a number of positions.
I have no problem with 2-3 over-30 guys. I think the goal is show noticeable improvement in '20 and over-30 guys buy 2-3 years to bring in and groom long-term solutions.
