I don't much care for vendettas and that's exactly what this appears to be. If the entire team was doping, which they were, then they were all on a level playing field. If they couldn't beat him, Oh Well! And I'm sure that his team wasn't the only team that was doping.
When all this happened, the tests that they had at the time, all showed negative results. I think someone just had it out for him and wasn't going to stop until they got what they wanted. I think that this is what happens to any athlete who is pushed to win at any cost. It happens in every pro sport, not just in cycling.
