Wouldn't You Know???

After all the hoopla... All the contract negotiations... All the media/press surrounding Manny Ramirez's return... He's been suspended for 50 games due to a violation of Major League Baseballs drug policy... Ramirez says, that he's never taken steroids before and that he was on a perscribed medicine from his doctor, and apparently there was a susbtance in the medication that was not allowed in the MLB...

My question is... If you're getting paid millions of dollars, wouldn't you do something like, oh I don't know... KNOW which medications you can take and can't take???
