No way, but he was extremely lucky to have only played Nadal
once (in the Aussie final) and he did not have to play Djokovic or Murray in either Slam and when healthy both are better players IMO
Normally he would have had to beat three of them in the Aussie as the #17 seed and at least two at Wimbledon.
It really helps to get a little lucky and have the best guys get upset or hurt, He took full advantage and with his enormous talent he won both.
If there was any doubt before, it seems safe to say now that he is the best player of all time based on his 19 Slam wins. I will say thet he and Rod Laver in their primes would have been some great tennis
With Djoker's elbow injury and Murray also apparently injured, he may well win the US Open. He is my favorite to win it, probably beating Nadal in the finals.
