Let me see if I've got this right. Ricco left Rossi, with whom he has a child, because he couldn't stand her doping. Now it turns out that her B sample was negative, so it's not clear whether she was doped or not. But it is clear that he was doping.
If that's the case, you have to wonder why he left her. Was it just personal reasons unconnected with cycling, or is he such a callous dickhead that he's prepared to dump her in order to put on show of innocence?
