I'll take that bet. USA has a slim chance, but it's far better than two-loss Poland.
Poland's big problem is Goal Differential.
Assuming Costa Rica beats Ecuador by 1, that means Poland must beat Costa Rica by two or more goals.
Then Germany would have to beat Ecuador by at least 3 goals for the Poles to get in.
For the US, they must beat Italy, then beat Ghana, then hope the Italians don't beat the Czechs.
For scenario for Poland seems a little more feasible than for the US.
The USA's attention has turned to the all-important clash vs. Italy, and assistant coach Glenn "Mooch" Myernick drops by Wednesday's episode of Studio 90 to preview the match
