Hawks are ahead of schedule, in the way that the Heat were, last year. Except the difference between Atlanta and Miami is that Atlanta's core is all on the same timeline, whereas Butler is not on the same timeline as the rest of those dudes, which resulted in Riley arguably making the wrong decision with Harden, having to choose between trusting the growth of his young guys, or going all-in on "win now."
Whether this season ends in a championship for Atlanta or not, they can afford to stay the course with what they have.
