On Monday evening, UFC world middleweight champion Anderson Silva starkly switched from mellow to malevolent in the blink of an eye, taking everybody, not least of all opponent Chael Sonnen, by surprise.
The performance-enhancing drug problem in mixed martial arts is bigger than many may appreciate. It is time for Olympic-style testing including random year around sampling and blood testing in elite MMA.
Normally, the chatter of Chael Sonnen would alarm me. However, in this instance, Sonnen seems to have hit the right tone between pre-fight deception and pre-fight hype. His words make me think he may have a sniff at victory.
