I agree, Djokovic is still "2.0" or whatever you name it.
Last year, he could've lost to Murray (on clay), to Nadal in Miami, to Federer at the USO.
You can't judge Djokovic's form solely on his winning steak or his losses. He played the best (arguably) two matches of his life just a month ago.........
it's the way he's winning these days if you want to look at it that way.......he barely got by murray and nadal in the AO as compared to last year's steamroll to the title.......he lost to murray on a fast court and isner on a slow court.......
a fact which many of us might not yet have realized - djokovic won just 1 title in the last 7 months.......he looks slower, less consistent and very beatable this year.......all that was expected anyway.......
it is just not possible to keep up that AO-USO level of 2011......it is extremely physical to persist with for a long period of time.......i have a feeling that he might completely go off the boil unable to keep up with the pressure of defending everywhere.......
miami, belgrade, rome, madrid, french open semis, wimbledon.......that's one hell of a defense and he's not as strong as nadal physically.......
