I sincerely hope I am completely wrong, but history has repeated itself a few times for the US women's 4x100m.
So, the prediction contest is:
1) Which athlete will drop the baton?
2) In which round will this happen?
Or, will anybody go out on a limb and say either
1) The US will get DQ'f for something else (ie, not exchanging the baton in the right area, false start, etc.)
2) The US will actually finish through the final without any DQ's.
I am going with Jeter dropping the baton in the final round (nothing against her, just my random pick).
