Simmons and Embiid are legitimate superstars.
I don't trust Embiid's health. While I don't wish an injury on him, I would not trust his knees to last long term. They been hurt before and most likely will be hurt again. Broken navicular bone and meniscus tear already. Now the meniscus tear should be fine but broken bones in feet have ended many a career.
Simmons is talented so is Embiid. But Simmons does not play with a ton of effort or drive.
As far as Fultz, I am in the camp that he won't ever amount to much given what we have seen thus far, consensus be danged.
I am old enough like many here to remember when the Sixers Celtics were a real rivalry. I just don't think the Process has enough leaders to get there. That being I hate the Sixers from the old days and I might not be the least biased person regarding them.
