To follow the baseball analogy.
Say you are the manager of the Red Sox. You do everything honestly... refuse dirty players etc.
Now you have the yankees as a team all corking their bats. As such they have huge advantages and are pretty much kicking your ass a lot of the time.
Perhaps the honest manager tired of the cheating and losing decides to let a few people who take steroids in to even things up.
Not a lot... just a few to make things competitive while he keeps honest players where he can. However lots of players see what the steroids do, and now the floodgate is off.
It's easy.
