This post clearly shows why we can't have a GOAT, or even a surface GOAT. Conditions, playing equipment, training techniques, supplements, depth of competition etc are always changing. Players can only really be considered the greatest of their own generation. This is why I don't consider Federer as GOAT, even while being a massive fan, or consider Nadal clay GOAT for the same reason. Both are greatest of their Era's though.
And we can only speculate what COULD or WOULD have happened. No one will ever really truly know.
