Newspapers in his homeland alleged that he had endangered his marriage with several liaisons, while John McEnroe said last year that the fallen world No 1 "had some off-court issues with the family".
McEnroe controversially invited a parallel between Djokovic and Tiger Woods, as examples of sportsmen whose form apparently disintegrated due to troubles on the domestic front. It is a comparison he has now thrown off.
This tournament has shown a version of Djokovic that some feared had gone for good: the consummate retriever, haring down every lost cause, trading blows with Rafael Nadal for the best part of 5½ hours, and ultimately reaching a fifth Wimbledon final that he won with room to spare against Anderson in the fierce sunshine.
Conspicuously, there has also been a reassertion of Djokovic the family man. While his wife Jelena was notably absent courtside at last year's Wimbledon, she was back front and centre for his victories here.
It was a narrative not explicitly stated in the questions Djokovic received last night "about everything you've been through these last 18 months". The man of the hour preferred to focus on his battle to recover from a serious elbow injury, but the restoration of peace and harmony at home has proved crucial in his return to the summit.
Between them, Federer, Nadal and Djokovic have now accumulated 50 grand slam titles, all in the space of 61 tournaments since Wimbledon 2003.
It is a level of dominance unprecedented in the modern game, and the fascination will be to see how close Djokovic, with his 13 majors, can push Federer, with 20.
It is a huge ask, not least when the Swiss gives little sign he is finished yet, but Djokovic has served notice at Wimbledon he is tapping back into a rich seam of inspiration. The last time he prevailed in London, in 2015, he added the next three slams.
He has found virtue in familiarity, ditching the experiments with celebrity coaches - Boris Becker and Andre Agassi have both come and gone - in favour of a reunion with Marian Vajda, his former trainer, and Gebhard Phil-Gritsch, his fitness expert.
"I love these guys," he said last night. In some ways, Djokovic has not so much rebounded from the brink as come full circle, ditching the high-profile entourage and embracing his most trusted lieutenants anew.
One moment yesterday stood out for Djokovic, far above any of his exploits on a baking court. It came after he had exchanged pleasantries with the Duke and Duchess of Cambridge, and headed off for his first round of television interviews.
In the room outside, his son Stefan bounded in for an embrace. It was a moment, Djokovic reflected, that he would treasure the most, one that would endure long after the glory faded. Even at 31, he is wise enough to appreciate that the older you get, the more it means.
