If KD has an issue with Nash, cool. Then KD should have an issue with Kyrie for being dismissive of the position as a whole.
KD has no leg to stand on to be critical of Marks for letting KD do whatever he wanted and if there was something KD wanted that Marks ignored, then KD a) needs to mention that and b) blame himself for not bringing it up and he and Kyrie had all the infinity stones with the Nets.
and nothing in terms of the team's direction changed between KD re-upping for 4 more years and today besides Kyrie not getting a similar extension.
