This is based on how good the teams can perform. Group play is full of oddness that sees strange results and performances, both for good and bad.

2. Netherlands
3. Brazil
4. Argentina
5. Chile

10. Costa Rica
11. Mexico

13. Uruguay (they're boned without Suarez)

16. Algeria
So yeah, I don't expect the US to go through to the final 8, but I do think that they have a decent shot at it. I just don't know that we're one of the best 8 teams in the world left. I hope it doesn't happen, but I think that Costa Rica will come back down to earth. They've been playing great, but I think that they were a bit underestimated and taken far too lightly (which may have been true of the US and Mexico as well).
Switzerland is too much of a one man show, and they got obliterated by France. Belgium feels like a team that could go deep if they figure out how to play smarter team ball. The individual talent is there, but they're scattered.
I might have Colombia too high, but I like them going through one more round, given that Uruguay is toothless without Suarez, though Diego Forlan might be able to stir up some magic, but it's not very likely.
