Miami maybe backing out or unwilling to trade away all of their younger talent. Word is they are starting to balk at the Bucks requests to add more to their proposed deal.
The Celtics are also still looking to trade for Giannis but are unwilling to part with Brown. I have heard if they part with Brown they will be looking to get at least one pick back. Either from the Bucks or from a third team in a trade. Not sure if this is true just what I have been told. Only one of the people I have talked with is saying this and he is not as reliable.
