Listen, I was very rude and I apologize for whatever I wrote.
That being said, in order to even clear enough space (this is in response to byennie's original comment regarding if we had $20 mil in cap space,) we would need to renounce all free agents, clear all cap holds, presumably get Baynes to agree to be traded.
S&T are just particularly tricky, because you have to not only get both teams to agree, but the player signing the contract would have to agree with the notion that the respective team would be losing liquidated assets.
I just cannot see Ainge even touching CP3's contract.
