In July 2011, he was still very good, considering how he'd just annihilated the field in the hardest GT in recent memory, plus the impending CAS suit that was hanging over his head. Then consider the crash and time lost to the odd application of the rules in TdF stage 1.
There is no proper discussion of Contador's form this year that can take place outside the clinic. There just isn't. No matter how many silly posts (not singling you out, CS, there are a lot of them) get written about how Contador has faded/waned/is getting older.
Contador had pretty damned good results this year when you consider the whole picture. And gets no credit for it, just gets called "Barabbas" by Walsh and called "old" by the fans. And no one appears to be interested in trying to figure out what AC's natural level actually is.
Yeah you pretty much nailed it here. Speculation of wanes is pointless. I repeat, he has not been the old Contador since giro 2011
We could see a return of the old AC overnight if he wanted to take the risk. It ain't age that happened to Contador this year.
