Kyrie's great at dribbling and shooting but terrible at damn near everything else. With his ability to break down defenses you'd think he'd be able to get opposing teams in foul trouble in short order, but the problem is he prefers low-percentage trick shots near the rim to drawing contact. For as many points as he scores he gives them right back at the defensive end, and dribbles the air out of the ball instead of facilitating the offense.
His leadership is absolute gutter-trash putrid. I'm a lifelong Celtics fan and he was the worst leader I've ever seen of any sport. Constantly threw teammates under the bus, mailed in playoff performances, lied to the fanbase, clashed with the media, and came off as the most pretentious contrarian doofus the whole time. I can't imagine even if he were to go to Philadelphia that someone like Joel Embiid would put up with his pseudo-woke BS for more than a quarter of the season.
