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.

However, having Durant certainly helps, they were pretty good until like this year, they even had a finals chance, and they lost, Bucks won, but they added Durant to that team which means that they are doing mighty fine and will be a good team in the end. Mavs are looking good too though, they could take on Suns on a 7 game series, maybe win, maybe lose, but they wouldn't be too bad for sure. It is always important to keep your cool whenever you can.
