Complicated scenarios for Group B. The winner of the group faces Mexico in the Round of 16, while the runner-up will play Uruguay.
Two teams from each group advance. A team gets 3 points for a win, 1 point for a draw. The first tiebreaker is goal-differential, the next is goals scored.
Team.........Pts..Goal-Diff..Goals-Scored
Argentina.....6......+4..........5
S. Korea......3......-1..........3
Greece........3......-1..........2
Nigeria.......0......-2..........1
At 2:30 ET, Argentina plays Greece on ESPN and Nigeria plays S. Korea on ESPN2.
Argentina advances unless they to lose by 3 goals to Greece AND South Korea wins by enough to make up the rest of the goal differential.
South Korea probably advances with a win (they will unless Greece wins by a larger margin, but not enough to kill Argentina's goal-diff), and they advance with a draw unless Greece defeats Argentina or gets a high-scoring draw.
If Greece wins by 3+ goals, they advance for sure. If they win by less than that, they advance unless South Korea also wins by at least the same margin. Greece can advance with a draw if Nigeria beats South Korea, or if South Korea also draws but Greece scores more goals today.
Nigeria, with zero points, actually advances with a win if Argentina beats Greece.
So, assuming Argentina wins, South Korea will finish second if they don't lose to Nigeria.
