Sometimes I wonder just how stupid athletes believe we are when it comes to drugs.

From Roger Clemens denying to this day he's never touched steroids to Manny Ramirez saying it was a personal reason why he tested positive for a fertility drug commonly used as a masking agent for performance-enhancing drugs to David Ortiz saying his reported positive test came from legal supplements and vitamins he did or didn't know he was taking, athletes denying drug use has become laughable.

And I'm just touching the surface with these examples.

My favorite story WAS tennis player Richard Gasquet saying -- and subsequently getting away with -- testing positive for cocaine last year came from kissing a woman who had the drug on her lips.

Now comes the saga of Tour de France champion Alberto Contador. The No. 1 cyclist in the world tested positive for a PED as he pedaled his way to his third Tour title. He now says the positive test for clenbuterol came as a result of eating meat that MAY have been laced with the illegal substance.

Tainted meat leading to a positive drug test? Really? Then, to paraphrase what a national radio personality said recently, I must be Arnold Schwarzenegger with the amount of beef I eat a week. I'm guessing the same can be said for a lot of people in the world.

Say what you will about those athletes who have come clean -- or been forced to come clean -- about their PED use, at least they're still not trying to insult our intelligence.
