Problems usually arise among these "value" players when they start losing badly. I get it that Kyrie or KD also hate losing but a lot of players always looks for someone or something to blame for their poor results. Not really taking much responsibility for the loss.
Alot of players have their own prime time and also have their deform period, it's actually facts in the game and can not be changed. When a team loses, they points out blame to each other instead of accepting defeats and move on. In the case of Kyrie, he needs more time to get back into shape and having a regular playing time to improve his performance in games. We all know that he's one of the sharp player in his team and some managers can't afford to lose him to his opponents.
They just need to move forward and forget about that bad performances, as long as they are willing to let go and come back strong.
with regard to Nets stars, they are still part of the top NBA stars and with them playing healthy, winning chance still high
as long as they are aiming with same goal together, no more attitude issue just enjoy playing together.
