4 years is a potential career ender though. He really only tested positive for EPO (which is the same thing Mosley got caught for).

And to be honest I have no problem with them throwing the book at guys who get busted doping. They need long, stiff punishments if they want to put a dent in the doping situation. But at least be consistent. Margarito got less time for using a tangible weapon in the ring.

When you hear he used 13 substances, that sounds like a lot but it's not really. There are a rediculous amount of different types of steroids for different purposes. I gaurentee you other dopers in the sport have experimented with as many or more different substances over the years.
