Yep. The above is why nobody other than the Lakers is currently attempting to trade for Kyrie. You can set aside the whacko flat earth nonsense, the wild conspiracy theories, and even the earnest political stances. Every NBA team will accept a player's activism and endure a player's most grating quirks if the player is talented enough, available enough, and if the locker room holds.
The problem with Irving is that he marches so recklessly to the beat of his own drum that he alienates himself from teammates, coaches, and front offices, and renders himself unavailable to play without consideration for the needs of the team. He may not play for any number of "personal reasons." He may not play because his individual choices are at odds with league rules or public policy. And he may not play because he's oft-injured and generally uninterested in returning to the court on anything but his own time table. Some of his absences are more justified than others, but regardless, the team he plays for gets left holding the bag.
And if Irving's lack of availability wasn't bad enough, his personality quirks also have a tendency to divide locker rooms. Despite the attention he draws to himself, he's never been a natural leader, and his very public quest for self-actualization seems to read as egocentrism to those around him. When notorious sulk extraordinaire James Harden demands a trade to get away from you because you're an even bigger malcontent than he is in the locker room, you know you've got a problem.
Regardless of his talent level, Kyrie Irving is really unreliable and a toxic presence on most teams. Front offices around the league have simply determined that he's not worth the headache. The Lakers are, of course, hoping that Lebron's prior stint with Irving might gift him with "Kyrie Whisperer" abilities, but it sure seems to me that Irving has only become more eccentric and mercurial in his attitudes since his time on the Cavaliers.
