Signed, another guy who's negotiated contracts for 30+ years. 
There really is an "art of the deal".
Absolutely. And sometimes, even if you do everything by the book, you can fail.
All it takes is a bad actor on one side, or an ignorant one, and you still fail to come away with the best outcome.
But with this Jaylen Brown deal, gosh, I just keep going back to "Sometimes the best deals are the ones you don't make."
That being said, I will get some entertainment value out of having these extra picks and imagining what can be done with them, and other picks, and other players, to make another championship contender.
