I'd say they're sincere. They honestly don't think Armstrong did anything wrong - certainly not in the doping department, which is what they'd be aware of. For them, it's just the way things were, the way the game was played. They might feel Armstrong is being singled out and persecuted unfairly.I Watch Cycling In July said:Hamilton also seemed very anxious to defend Lance in the 60min interview. I'm never quite sure how to take such comments. It's difficult to tell if they are expressing honest opinions, or attempting to protect themselves from the inevitable accusations of bitterness or jealousy.
