I don't think the CP3 move carried much risk at all. And as for the Barkley comparison... if we were getting Durant when he was 29 and durable, like Barkley was, things would be different.
When I say that it was insanity to think the KD trade would work for us when similar trades have almost all been disastrous, I am talking about these "4 firsts and other good players for a star" trades.
Trades structured like that have virtually all been totally ruinous for the team getting the "star", and even worse, the other "stars" in those trades were considerably younger and more durable than KD at the time of those deals.
So we tried something that has been done before around the league several times, virtually always ending in total failure and we did it for the oldest and least durable player ever moved in one of those deals.
