With Phoenix I'm starting to think either that guys don't like playing with Eric Bledsoe, or Jeff Hornacek isn't very good at managing personalities.
Considering the success that team has enjoyed playing a seemlingly fun, up-tempo style, you wouldn't expect there to be a negative atmosphere surrounding them, but there has been for most of the last year.
The two point guard offense is a cool idea, but I think you need to make sure the guys you bring in are ready to buy in. At times watching Phoenix it seems like two guys who want to have sole control of the offense simply taking turns.
