There are some sports where it is so prevalent that it must be ignored for the sake of the popularity of the sport. They all use something..
Look at the NFL. It is full of illegal Peds. But the image of the sport is not being tarnished by bad publicity and senate hearings like MLB had to go through. That's why I give Goodell credit. Selig hurt the game of baseball. Goodell protected football.
