The Embiid thing is definitely demonstrating that creating a culture of professionalism and targeting the right guys is a factor you must consider, even if talent, at the end of the day, is the most important thing by far.
The Sixers will still be fine if a couple of these draft picks hit and they start surrounding them with overpaid role players. Hinkie, like Morey, has shown he can find role players off the bargain bin. They'll have to overpay guys to go there, but that will change if they have a couple of young stars and they make a playoff appearance.
All of the negativity will dissipate once there's some excitement around the team. And it can turn around really quickly. Look at how quickly it happened for the Bucks.
If Okafor isn't as good as they hope, Embiid never comes back from this injury, and Saric never comes over, then you start to wonder if they clean house and over-correct in the other direction like Charlotte.
