Gambo is letting more things "spill". He 100% has a contact in the FO because he knew things like the Nets not being interested in the Nets where alleged insiders had Ayton as part of a package for Durant. He said the Suns are telling him that the Suns never offered Bridges. Why? Because the moment the Nets expressed no interest in Ayton any hopes for a deal were dead from that moment on unless they could get another team involved.
That appears to be where the Suns have spent the bulk of their time since this all started and nothing ever materialized despite hunting for another team to help.
From the START, the Nets told the Suns they wanted Ruby Gobert type deal or no deal at all. So, the Suns were never in it nor did they make a formal offer because the Nets were upfront with the Suns from the get-go and never wavered. There were no negotiations and the Suns NEVER (despite a certain insiders Tweets) ever had what the Nets wanted. Ever.
So, it sounds like the Suns were depending on Ayton interest early on and the Nets killed that right away. So the Suns were never in the right place and the right time and they never had an opportunity to get KD because of the lack of interest in Ayton and not having what the Nets wanted.
