If the Clippers could get KG for Jordan and Bledsoe, they should jump at it. They'd have a real chance at two titles. The Clips probably will lose Bledsoe to free agency soon. Losing Jordan long term will hurt, but in Los Angeles, with a banner or two in the rafters and cap room when KO finally retires, they should be able to attract a FA replacement.
The way this Celtics team rebounds and plays interior defense, they have almost no chance at a title this year. Bledsoe and Jordan is probably the best package they could get for Garnett. The GM has to make that trade if offered, unless he believes that the Celtics would have a solid chance at a title this year and next.
Ditto the Barnes/Pierce with the Warriors. Pierce has shown that he's a still a top 5 SF, but he's getting older and his championship window is closing here. Adding Bledsoe, Jordan and Barnes is a real good start to the rebuilding process. I''m not under any illusions that rebuilding is going to be easy. It's going to happen eventually, whether the Cs trade KG and PP, or they ride off into the sunset in green after a couple of 44 win seasons an early playoff exits.
