They have a limited time to present the story, so it's understandable that they leave things out. I thought they conveyed how arrogant he was, even as a really young competitor. They didn't sufficiently illustrate the history of using people and then casting them aside, as he did with one interviewee, Rick Crawford.
I like that they put doping in perspective: it's a brutally hard sport where we expect the riders to do things that cannot be done on bread and water alone, thus doping in some form has been there almost since the beginning. That isn't necessarily a defense, just a recognition that what he was doing was typical. I think some folks are like me and just had a problem with him trying to destroy people and the level to which he took this lie, bamboozling a lot of naive people, in particular, some folks dealing with cancer.
I think one impression that viewers might get is that Armstrong was a phenom in Europe when he first arrived. He was very talented, but there were riders his age at that time from various European countries with better credentials and seen as more gifted. At that time, he was not seen as America's next big Tour hope. That was Bobby Julich. Had he come from Belgium, Spain, Italy at that time, the hype would've been considerably less. The simple fact is that some guys benefited much more from EPO than others. I think Armstrong's VO2 max was measured in the high 70s at some point. A tremendous number compared to the general population, and even most athletes, but within the pro peloton, it was lower than you would expect for someone who would go on to win seven Tours de France. Ivan Basso, who was interviewed in Part 1, had a VO2 of 84 and Greg Lemond famously had a VO2 of 92. Miguel Indurain's was like 88. And that's the number that cycling coaches looked at to determine which junior riders had what it took to ride in the pro peloton.
I used to go on rants about this guy. What's the point? I'm skeptical that he's really changed much, but who knows? His race analysis is spot on. I've listened to his Tour podcasts in the past and he's really good at it. If I owned a network covering the sport, I'd hire him in a second as a commentator.
