He has been very carefully versed on what he can and can't say without implicating himself as a criminal.
I watched it this morning as it aired and even though everybody expected it hearing the "Yes, Yes, Yes, Yes, Yes" was still a little shocking. Even up until then, I don't think I thought he would ever admit it. Not that I didn't think he did it, but that I didn't think he could own up.
People seem to be disappointed with his confession. It's hard to imagine how he could have come across that would've pleased people, but he seemed to straddle the line between not genuine enough and not apologetic enough.
The apologies he tacked onto the end of almost every sentence seemed a little hollow. The details are where he seemed to tell the truth, he seemed almost brazen. He kept referring to it as "what I did" or "that thing" never really saying it which tells me he hasn't really accepted it yet. I agree with LeMond that he feels no remorse. As usual, he's only sorry he got caught. That much was obvious when he talked about regretting his comeback.
I'm just thumbing through my copy of "The Lance Armstrong Training Program" to see where I missed the chapters on EPO, HGH and Testosterone.
