The egg was used during 2010, no? Rather than the end of the year/early 2011. I think Nole's ascent to greatness from late 2010 to the present day has myriad factors, far beyond mere improvement in fitness.
Ascent to greatness in 2010? He won a tight match with a bucketload of mistakes against Fed at the USO and then proceeded to bend over to Nadal in the final. Winning DC against the French is hardly greatness...
The reason I mentioned the egg was because it can be used to mask the use of EPO, not that it in itself is illegal. Of course, I cannot prove my suspicions but this was the case with Cheatstrong for many years and you can see the result in Oprah's show.
Finally, Djokovic's improvement in fitness had all to do with his success in 2011 and his 2012 AO win in the final.
in other words, "i'm a fanboy so i'll only raise doping suspicions on the players i dislike".
Not that you deserve a reply but no. I just don't think his reasoning makes sense. You can have mono and play tennis and win a small on the surface you made your breakthrough. If you want to point some other points he made that make more sense feel free.
