Kyrie is a good player, noone can deny that. He's just not really a team player IMO.
You are right, the Kyrie we have known since then is more on solo play.
But here at the Dallas Mavericks, many have doubted that Kyrie isn't fit with Luka since they are both ISO players. I'm one of those doubters and want Kyrie to be traded instead as I think he will just destroy the chemistry of the Mavericks. But that was all changed and I think Luka gives way as a playmaker for Kyrie. Since teams knew that Kyrie always acted solo on most plays, he was sometimes doubled or tripled on defense, and that made other scorers of the Mavericks always free at the perimeter.
That's why it didn't work with Lebron for too long, didn't work with KD,
There is a personal issue between Lebron James and Kyrie Irving that's why the latter asked for a trade. But before that, their Cleveland Cavaliers championship year is great proof that if LBJ and Kyrie work together as a team, they are a threat.
He also had personal issues with the Brooklyn Nets (a crybaby lol) before that's why he didn't work well with Kevin Durant back then. Then later on, Durant also had an issue with the management there and the rest is history.
