I assume that a significant percentage of athletes in all sports use some form of banned performance-enhancing substance.
Athletes will do anything to get an edge. If Holyfield did use a banned substance, he won't be the first and he'll hardly be the last. I'm sure he fought opponents during his career that were using banned substances as well.
Personally, I don't care if athletes use steroids and/or HGH. I understand that there needs to be testing to make it look like it's wrong, and I know it's dangerous for kids to think using substances is necessary to succeed.
But I just accept steroids/HGH as something that will always be a part of sports. There's lots of money at stake, athletes are going to do whatever they need to do to be the best. It's just the way it is.
I don't care if Evander took something, and I don't care if he didn't either.
