Is Djokovic now the greatest ever?
 

It's hard to say no.

Absolutely. He has the chance at a Golden Slam this year which is incredible

With Federer pretty much done, Nadal not likely to win again except on clay, and the new guard not really up to Novak's level yet, it's hard to imagine a likely candidate to beat him. Of course, they don't play on paper so who knows. But he still seems to be in his absolute prime, and capable of winning seemingly every crucial point.

Very low production RC by the way.

I used to work at Tennis Canada where we put on the Rogers Cup every year and was lucky enough to spend a lot of time with Nole when he came to town. Great guy and always signed a few things for me.

It was already wrapped up when he won the French. Now he's just adding on

Djokovic record in GS matches:
Vs Federer 11-6
Vs Nadal 7-10

Nadal record:
Vs Djokovic 10-7
Vs Federer 10-4

Federer record:
Vs Djokovic 6-11
Vs Nadal 4-10

To me, greatest ever is a toss up between Nadal and Djokovic, Federer certainly isn't.

Djokovic is the only player to beat Nadal and Federer at all 4 GS. He certainly has a case to greatest ever.

Nadal obliterates everyone on clay, on the one hand of course it counts, on the other hand it somewhat skews his record. I believe 13 of his 20 GS titles are the French.

Federer's claim is based on 8 Wimbeldons and 5 consecutive US Opens, among other things.
