If we permit cyclists cheats then the LA phenomenom whereby a certain rider wins the TdF every year for several years will become commonplace. I find that very tedious, just as I find football cheats tedious.
Of course the other issue with concentrating on the use of PEDs and a single rider is that other things may have possibly have been missed.
Do the recent revelations of the Vinokourov bribery allegations and fixing of a classic race open up a new line of inquiry.
Given the corruption in the USPS team, and the "win at any cost" ethos.......can we be sure there were no other irregularities?
