Drugs may not explain talent but they certainly exploit talent. As was pointed out earlier, his numbers exploded when naturally they should have been falling. That effect did not come from all those years of practice.
I don't think anybody here would disagree that Barry is loaded with talent. However, his admittance to using performance enhancing drugs sheds a negative light on all of his accomplishments. That is actually kind of sad.
The numbers before were still better than average. The drugs may have helped, I don't really know what he really used, and what he really believed them to be. But he also has had himself on a strenuous work out routine of over 4 hours per day for many years, which may have helped as well.
On the contrary to what you say, MANY here disagree that he is loaded with talent. Many people, led by the MSM, have had a campaign to tear him down for much of his career. His dislike of the media has been well documented, and as most of us on FR know, the media can do a pretty good job of tearing people down whether they be sports personalities or politicians. He has been portrayed as less than pleasant, so many like to use him as a whipping boy. Technically he has not admitted to using enhancing drugs, which is part of what annoys folks. I do agree with you that using anything to enhance himself does shed a negative light, and it is sad. But I don't think it should bring out the venom many here show.
