I haven't read the article, and I don't need to.
The problem with Bolt is that he BOTH:
1) is likely one of the best-ever 100m sprinters, cleanly, if not THE best ever; and
2) is likely do have doped during his career.
I've laid it out elsewhere on this board:
1) Bolt's goofed and negative-leaned 9.69 in Beijing 2008, his 9.58 in Berlin 2009, and his 9.63 in London 2012 were all likely doped performances; and
2) Bolt's 9.76 (-0.1) in Rome 2012 is possibly the single best-ever clean 100m performance.
Bolt, or whoever has been advising him, has been smart.
During the season, he doesn't need to use, because while training, he is essentially as good as anybody else even if those other athletes are doped, except for on occasion somebody like Powell or Blake who might clip him by a trivial amount of time. He can and does win races, and even if he loses, he only loses by a trivial amount, and only to one of the other top 4.
No problem, mon.
The problem comes when those other guys get into shape for a championship, IMO by doping. By "those other guys" I'm talking Gay and Blake. Bolt doesn't have to worry about Powell, because he's in his head, and knows that he will self-destruct in any case. He also doesn't have to worry about Gatlin, because Gatlin's best, even when doped, is still very slightly worse than Bolt's likely clean best.
Blake and Gay are dangerous to Bolt, because doped, they are both faster than Bolt is clean. In 2008, Bolt thought that he was going to have Gay to worry about, and because Powell was still a concept, he probably worried about him, too. He realized by 65m that he needn't have worried about Powell, the only guy left who could present a problem, and started goofing to the finish. He would have gone 9.6 on that day had he run through the line.
In 2009, Bolt did have to worry about Gay, and he knew it. He used again, because he knew that if he did he could lay down a 9.6, which would still handily beat anything that Gay had shown he could put up while doped--and he also knew that Gay would now be better than what he could do, cleanly.
I don't know what happened in 2011. Judging by what he did in the 200m, Bolt could quite possibly have won the 100m over Blake, but I don't know if he was ready for Blake to have advanced to threat position so quickly. Blake's time in the Daegu final adjusts to only 9.83, a time that Bolt could still beat cleanly, but the danger was that Blake was progressing, after Daegu improving to two windless 9.82's, 3 days apart, in September. I don't know if Bolt used or not in 2011.
In 2012, Bolt really had to worry about Blake, given his two windless 9.82's at the end of 2011, and his 9.75 in Kingston. That 9.75 was a 9.80 basic, and Blake was improving, to a the point that he was likely very near what Bolt could do cleanly. That was way too risky, so Bolt used, and he was back to 9.6, outside the performance envelope of even a heavily-doped Blake.
The other smart thing is that I don't think that he dopes as massively as others. I think there's a pretty good argument to be made that he can, and has, gone around 9.75 cleanly. Doping down to 9.6 is only about .15, a far cry from the relatively quick ~.50 improvement seen in many sprinters. Plain fitness can get him down to 9.75, and even a single relatively modest cycle could drop him by .15, which is all he needs to be unbeatable by any of his competitors, either now or on the horizon.
So, they have been sly and judicious in their use of doping, using it just to ensure championships--if he didn't win them, some other doper would, so what the heck.
They have also been tight-lipped about it, making sure to get whatever treatment he is getting from a licensed doctor, who is bound to preserve the doctor-patient confidentiality on behalf of his patient.
Very smart. Bolt is the most dangerous kind of doper, because he is the most difficult to detect.
Very neat. Bolt is also the most desirable kind of doper, because he is the most difficult to detect.
Childhood phenom? Yes.
Quite possibly the clean fastest-ever and therefore an "outlier"? Yes.
Doped at 9.69, 9.58, and 9.63? Yes.
Smartly selective? Yes.
Desirable? Yes.
It seems like a tidy story, with little supporting evidence, but there is substantial evidence, all written already on this board. He IS track and field, even in the USA--well before Gay's positive, when I first stated on here that Bolt WAS track and field, I asked a bunch of average joe's and joanne's these 2 questions, in this order:
1) who is Tyson Gay?
2) who is Usain Bolt?
Out of dozens and dozens of people, only one knew without prompting who Gay was, and that person was a national-class swimmer athlete. EVERYBODY, including 9-year-old kids, and excluding an octagenerian, knew who Bolt was.
Anecdotal, yes, but it was in the USA, and it was good enough for me.
Bolt IS the public face of track and field, even in the USA. He is BOTH quite possibly the clean fastest-ever, and the most successful championship doper.
