Well, that's funny that you say that, L3333.
The NFL has had harsher steroid penalties than Major League Baseball. Major League Baseball has only recently come into the limelight with steroid accusations and admittances from stars such as Barry Bonds, Mark McGwire, Sammy Sosa, Jason Giambi, Alex Rodriguez, and others. Baseball's steroid policies made testing optional through the late 90s and only since has become mandatory.
It is worth noting that more money is made each year by doctors and scientists trying to hide steroids than their colleagues trying to cure cancer, but football's drug problem has been cocaine, not so much steroids (a few exceptions to every rule, of course).
