“I see this story as צדיק גוזר.”
You should really ask yourself. Do you really think the Rambam would have accepted this sort of logic as proof. Not that I am doubting the very story, but if you would like to prove the point of צדיק גוזר – you cannot bring any stories that we know only by mere storytelling tales. There are much better sources for that. Moreover, from the stories it is certain that in any way whether he won or lost, you could have pinned the very same above צדיק גוזר on any side.
