"Things haven't been going well for [Landis]," said Strickland. "His racing career is suffering. He's admitted in public that his legal troubles have more or less ruined him financially."
Armstrong said, "If I could give you one word to sum all this up, it's credibility. Floyd lost his credibility a long time ago."
The allegations against Armstrong will most likely not have much effect on his wider reputation, Strickland said.
"This is not going to sway anyone's opinion," he said. "I really believe that people have their opinions of Lance, and they look for evidence to support that."
Armstrong said that Landis's disclosure does not change his plans to compete in this year's Tour de France, joking with reporters that he didn't expect Floyd to be in France telling the story. There is a warrant for Landis' arrest in France, related to charges that he hacked into an anti-doping lab's computer.
Armstrong also said he is just one of several high-profile cyclists caught up in Landis's accusations.
"It's very sad. I think at one point or another, all of us implicated have cared about Floyd," Armstrong said. "I don't want to make a personal attack on Floyd Landis. I don't think he's a good guy or a bad guy. I certainly think he has some issues."
