Is everyone on dope?

To borrow from something Russell Hedges said in the office earlier today, "Is everyone in sports on dope?"

Think about it. Floyd Landis fails a doping test in the Tour de France. Now sprinter Justin Gatlin fails a dope test. Then there's baseball with its burgeoning HGH/steroids problem.

It's enough to make anyone shake there head when trying to figure out who, if anyone, in sports is clean anymore.
