Why Miami does this?
They can't compete now, there is no way the beat teams like Boston, Knicks, Orlando, OKC...
They dont have enough assets to trade for a star that could makes a difference and make them contenders
There is no point on being a second round exit.
Miami already have a promising young core with Herro (24), Jaquez (23), Jovic (21) and Ware (20). Add players like Castle (20), Smith (21), Thompson (21) and Sochan (21) and this team could be a really good team in a few years.
This is without including the picks, Miami is one of the best teams drafting and developing talent. Spo could do magic with this hypothetical young team.
