At some point you at least have to wonder if trading for Kyrie while giving up IT, Crowder and a pick is a good idea. Is Irving an immature, locker room problem with an out of control ego? You at least have to consider this and do a ton of investigating to see if its true if you're thinking about trading for him.
Now, its extremely possible Irving just has personal issues going on with a team mate or two and has had it with the organization seeming to bow to the wishes of his team mates and doing things that Kyrie doesn't agree with. He could be a great team mate and great professional and hence someone you want to build around. Thats completely possible.
But you have to at least wonder if its not.
