yeah best of 3 with pk's each game if needed is a really dumb way to go about it. conceivably st louis could beat us 5-0 sunday, we could turnaround the following game and win a 0-0 draw in pk's, and then turn around with another 0-0 draw, win in pk's, and advance without scoring a goal in open play vs 5 for st louis in that scenario. pretty hilarious and just us soccer trying to appeal to non soccer fans i guess. just play the home and home with aggregate scoring.
