If a Kawhi/Randle deal became available using only Hayward and Morris, you better believe Ainge would jump on it. I realize it would paint a very bad picture for agents/FAs, but does it really matter when you have an elite team with no cap space to come for years? Throw in a Horford/Jaylen/Sac pick deal for AD and you have an unstoppable core for years to come.
I realize in saying this it sounds like I am not excited to have Hayward on the Cs - I really am! But, Kawhi is definitely better than Hayward and you have to take these kinds of deals when they are offered. In this case, I see no way it is.
