what about floyd? He started at 106.He was also 16 at the time. Unless I'm mistaken, he fought most of his early pro career at 130, and he's never really been known for his brutal beatings or knockouts at welterweight.
But no, I wouldn't be too shocked if it turned out he was taking PEDs. As I say, I'd be more surprised to find out that any top fighter isn't juicing than when I read about them getting caught. It's a business, and the top executives need their star attractions in the ring and bringing in money, dirty or not. It's in everybody's interest if we all turn a blind eye.
I should point out that I'm fairly neutral in the whole Floyd/Pac war (I would like to see them fight though.) It's a business at the end of the day.
Pacquiao has been juicing since the De La Hoya fight at the very latest. Anyone who has no problem with a former flyweight knocking out career top-10 welterweights is being deliberately blind.
I'm genuinely surprised every time a boxer tests negative for PEDs.
Tyson made his name beating up bums and faded champions, and got found out every time he faced decent opposition.
Boxing is an entertainment business first and foremost, and Klitschko/Ward/Rigo/whoever have no basis for complaint when they don't get the recognition they (or their supporters) feel they deserve.
