To add to what MattM said, the ridiculous bracketing is actually a regular topic of discussion. It's not only a random draw (which I don't like, but I could get over), but it pushes ALL the byes to one side of the bracket. At the Olympics, men's weights will have 19-20 wrestlers and women's will have 18-19. So, a typical men's weight will have 8 guys on one side and 11-12 on the other. This significantly increases the chances that the best 2 guys don't meet in the final. It's even worse at other tournaments, where there may be 24 guys--resulting in 16 on one side and 8 on the other. It's downright silly. You can easily have the 15th best guy in the semi-finals with this system.
I will say this, though; for the Olympics, the worldwide qualifying system was stringent enough that you're not going to have any non-wrestling nations occupying semi-finals spots. There will only be 2 or 3 potential "gimme" opponents in each weight.
