Novak Slam is not even top three. Great achievement and all but in a very weak era. Laver's two calendar year GS and Federer slam count are a whole another story, and I'd put La Décima on par with the Novak slam, considering the degree of consistency and domination required to dominate a slam for a decade.
Well, the "in a very weak era" is where I stop reading.
Anyway, better to leave this thread, too much off topic.
