Goat Herd Elder Statesman, might be the best title for Laver. His record stands alone for men's tennis, with two CYGSlams (Calendar Year Grand Slams). If all we do is count slam totals, we ignore all the other statistics.
Many tennis watchers say that Laver would never be able to hold up against the current talent like Rafa and Novak. I disagree.
It's impossible to make valid direct comparisons because players from the past conformed their methods to the conditions present at the time. Applying current standards against the past is a common cognitive bias.
