I would just be happy if Kyrie would keep his mouth shut and dribble the ball less - Isaiah Thomas was not seen as the team leader when he was here - just as our most explosive scorer. Why can't Irving be happy being a great scoring guard in the league, an all-star and help a team win multiple titles, the Boston Celtics no less. That would be enough to get your #11 retired. Problem is, Kyrie Irving, by nature, is a restless soul. He is always going to find discontent in his current circumstance, for whatever reason that is. He gets in his own way.
You do realize Isaiah Thomas's big mouth, and backing the 'Brinks Truck,' comments inevitably led to his departure from the Celtics?
The opportunity to acquire Irving is what led to his departure. Ainge would have looked to make the deal even if IT hadn't injured his hip. Also, Danny Ainge couldn't have cared less about IT's comments.
As for comparisons between IT and Irving, the major difference is that IT was consistently an emotional player who wore his heart on his sleeve. He played hard, spoke loud, and carried himself with the same demeanor at all times. Kyrie's mood is much more inconsistent and unpredictable.
I'm not anti-Irving but I think it's fair to assume that the chemistry of this team would be completely different if Irving shared IT's personality.
