This Summer, Danny will not have enough cap room to sign a max free agent. However, if Danny renounces the rights to Olynyk and Rozier he will have around 26-27 Million. Drummond makes almost exactly that the next couple years.
Anyways I can see us trading a combination of younger players, both Nets picks and guys like Amir and Zeller to pull off two massive trades.
Our linup would be something like Thomas, Smart, Butler, Horford, Drummond. That team is better than the Cavs imo. And would challenge GS with their elite guard defense and unmatched size.
