Booker has always been a bit of a weak trash talker, and that will continue to be like that for a long time considering that's a bit about someone's character and not something about their talent.
Booker and Doncic's argument was funny, but it was clear that it wouldn't grow any further. As long as there is no physical violence in this regard, I find such quarrels amusing.
Phoenix was a really dangerous team, as you all said. Having both Durant and Booker on the team offers more offensive options. They became one of the duos that scored 35 points each. It's hard to defend that. A healthy Phoenix will pose a threat to all opponents.
