Boxing isn't the only sport, but I agree that this list is disappointing to say the least. Here in the U.S. Major League Baseball has and is still going through a major dark spot in that sport's history with PED's. They have a lot of legends as well that have had PED issues, and one of the biggest stars of the early 2000's ( Alex Rodrigez) is about to be crushed with penalties. It's more of a global sports problem in which boxing is not immune to. Look at cycling too. A mess.
