Because Laver did not do it twice in the Open Era. Pretty simple. Laver and Djokovic are the only two male players in the OE to have done it and nobody did it twice in the OE.Please explain how Laver accomplished the CYGS twice and is still almost universally considered beneath Fed in the GOAT sweepstakes. But Novak going fpr the "NCYGS" twice (if he does it) nets him 16 slams, but he vaults over Fed??
Anxiously awaiting the explanation on this.
