This person would definitely be up for the GOAT position, and won't be forgotten easily. Back to back CYGSs will be something to remember, but then again you have the story of Ms. Connolly.
In the future, after this hypothetical player has died, I feel a majority of people will judge by what this player had done, instead of what this player could have done. It's sort of like a Bjorn Borg like way of judging things.
This player would be up there for achievements GOATs, and probably top for potential GOAT discussions.
