They barely test in football when you compare it to how many tests are done in cycling.
What worries me about Mo is that he lied about the injections, they weren't on his medical records and he didn't declare them on his doping control form. But we have to believe his word when he says it was below the specified amount. He can't prove he didn't break the rules but we (at the moment) can't prove he did.
I think there is more to come out, especially as he is a current runner. And he's rocking the Lance cover story - 'never failed a test'.
