Is the OP having this frantic debate in his mind.
His "controversy" seems sort of imagined. Certainly, in a Fed vs. Sampras GOAT debate, there are still a group of Sampras backers. But, most of them can at least concede that Fed as GOAT has a legit foundation, and can understand the argument in favor of Fed. Moreover, I'm betting that there are still many more Fed backers than Sampras backers.
So, the all this talk about myths seems a bit overwrought.
