It just looks like Anthony Davis was the wrong target from the beginning.
First off, it looks like Danny Ainge thinks that the KG method will work every time he targets a player. Doesn't work that way.
It worked for the KG trade. Didn't work this time.
New Orleans wasn't willing to trade him. THEN, when Davis requested a trade, Ainge couldn't make the move without dealing Kyrie.
And then, Davis' agent basically said to the Celtics, "not interested."
So, the whole situation was just a complete mess from the very beginning.
Ainge missed the boat on Kawhil and he totally misread the AD saga.
As for doing his due diligence, I don't think he is, otherwise all these things wouldn't be backfiring on him.
