Gonna be a rough early call.
We can do this easily, we match up well.
Only tough part is cheering on the Italians...woof!
Easy Way: USA and Italy wins (ITA 7 pts, USA 4 pts)
Hard Way: USA wins, Czechs win, and the combined margin of USA and Czech victories is six or more goals (example: USA 2-0, CZE 4-0). (CZE 6 pts; USA 4 pts, one-goal advantage GD)
Harder Way: USA wins by two goals and scores three more goals than Italy, Czechs win by three goals (example: USA 3-1, CZE 3-0). (CZE 6 pts, USA 4 pts, equal GD, one-goal advantage GF)
Much Harder Way: USA wins by three goals, Czechs win by two goals. (CZE 6 pts; USA 4 pts, 0 GD, one-goal advantage GF)
Obscenely Difficult Way: USA wins by four and scores three (or more) more goals than the Czechs, Czechs draw (example: USA 4-0, CZE 1-1). (ITA 5 pts; USA 4 pts, +1 GD, one-goal advantage GF)
In-Their-Dreams Way: USA wins by five or more. (ITA or CZE wins; USA gets second with 4 pts, +2 GD)
You've-Gotta-Be-Kidding-Me Way: USA wins by two goals, Czechs win by three goals, USA wins drawing of lots. (CZE 6 pts; USA and ITA: 4 pts, -1 GD, equal GF, head-to-head match tied 1-1, equal GF+GA)
Bottom line: root for Italy to either win or lose big.
