If the hosts were cycling guys, then yes it's deflection. But they're not. They are people on the outside throwing stones at him, whilst standing in a carefully constructed glass house.
There is doping in cycling, lots of it, and Óscar Pereiro will have seen it first hand, will have been it first hand. But he's also not stupid, and he knows that there is doping in football. And he knows that it is treated very differently which is why nobody talks about it, nobody knows about it. And whether he doped or not, it doesn't change the hypocrisy or the ignorance shown by those around him here. He was well within his rights to focus conversation not on himself, or Alejandro Valverde or Alberto Contador, but on Zinedine Zidane, Carlos Gurpegui and Pep Guardiola.
