perfectly said, only question about that theory is why nobody comes forward to spill the beans? with so many people involved someone must grow a conscience at some point and blow the whistle.
That is the biggest question for me also. There are journalists who try to investigate and write about this topic but the attention they get is rather small. And I guess it is just difficult to do something against people that possess so much power.
Look at that whole Eufemiano Fuentes story e.g. They busted the biggest cycling athletes and found all possible evidence to get them. But there were also rumors about Real and Barca being involved and having connections to Fuentes. But when it got tricky there were no further findings, all of a sudden blood samples disappeared etc.
I could be totally wrong and I am just guessing but for me personally it is certain that the world's best athletes in major sports all have something to do with doping.
I mean I love sports and especially football, play it, watch it, talk about it, read about it, think about it basically every day but it would be a huge surprise if that is not the case.
