As you can see from this aggregated list of top NBA players across websites (shoutout to u/Skippy1813 for the awesome spreadsheet!), essentially every site has KD above Booker. Only 1 site (Action) has Booker a spot above KD.
Also when Reddit voted on the best players in the offseason, they had KD at #4 and Booker at #14
Do you still agree that he is the best player on the Suns?
Yeah Durant is better. He’s a better scorer and defender
