While there were a few surprises to kick off the 2016 Summer Olympics, the knockout stage is where the results really matter.
Top contenders like the United States, Brazil and Germany had setbacks in the preliminary round, while Sweden and Australia were fortunate just to advance as the third-place teams in their group. However, few should actually be surprised by the eight teams remaining in the field.
The reality is it doesn't matter what a team did to get to this point, just what happens going forward. One loss in the quarterfinals ends any chance of medaling, a horrifying thought for many top contenders.
