Doc was destined to get canned after they lost, but to me the most damning indictment against him was publicly crapping on Simmons and throwing him to the wolves. That also, arguably, diminished his value further, so it hurt the team, too. Now, maybe Simmons was too far gone at that point to be rescued, but it seemed harsh at the time. Given Simmons' plummet, though, Morey turning a completely lost player into Harden was pure wizardry.
But most of these narratives people have are fickle and creations of the mind. If the Sixers had won game 6, the narrative would have been Embiid has taken the next step, and Doc has exorcised his demons in late series situations (at least some of them). We'd have pages upon pages on this board about how overrated Tatum is, how we have a coach who doesn't know X's and O's, and a roster that needs new faces. Hell, even on a Celtics podcast John Karalis spent almost an entire episode trashing the Sixers and their star players rather than focusing on the accomplishments of his own team.
The Sixers played well. Doc coached fine. Four minutes changed everything.
