TP to the OP. Thanks so much for posting this; Ainge's thoughts on the matter are something I've been very curious to learn about.
It seems like it really boiled down to GS just being a better team than BOS, coupled with an apparent desire by KD to not be "the man" and not shoulder so much pressure. I'm disappointed we didn't get him, but I'm pleased that, as far as I can see, Ainge & Co. did everything humanly possible to get him.
