It is very obvious you don't understand the CBA and the Salary Cap.
To get below the CAP you have to renounce all Exceptions - Bird and the TPE. Also, it's tricky to go below the Salary Cap to sign a FA and then use the MLE, it can be done but not in your scenario. Bradley or Bayless could not be renounced. And I can't see anyway you can get below without renouncing them.
So Bradley and Bayless are gone. And besides AB wants 8M not 6.5M, not saying he'll get but in your ideal team he's gone when you renounce him to get below the Salary Cap.
Further, there is no way Melo is signing for 15M - GUARANTEED.
Nor is Gortat signing for 9M. Also Wash is not doing a S&T Green for Gortat. Why would they? They just made the playoffs and he and Nene play well together.
Also, what did you give up for KLove besides the players. How many first round picks?
Sorry can't remember how you got Bellini, but can't really see him leaving SA, especially if they win a ring.
This whole proposal is SILLY. You really need to read Larry Coons FAQ on the Salary Cap.
And by the way the total Salary for that team is 76M you can't subtract TPE. It just allows you to trade for a player making that much money + 100K. We have a 10.3 TPE so we can add a player for a max of 10.4M.
Your Ideal and Realistic Roster is just SILLY. Pls read Larry Coons FAQ on the NBA Salary Cap.
