As already posted (by me) in the World Cup draw thread
Those looking to the Round of 32 would see that there are 5 possible Round of 32 fixtures that Group D teams may qualify for
Match 74: June 29 Boston - Winner Group E vs Best 3rd place Group A/B/C/D/F
Match 77: June 30 NY - Winner Group I vs Best 3rd place Group C/D/F/G/H
Match 81: July 1 San Francisco (no travel after last Group stage game) - Winner Group D vs Best 3rd place Group B/E/F/I/J
Match 87: July 3 Kansas City - Winner Group K vs Best 3rd place Group D/E/I/J/L
Match 88: July 3 Dallas - Runner-up Group D vs Runner-up Group G
Being Group Runner Up is a set opponent (tbd) and a set city (Dallas) who we will know as at the 25 June as Groupd D and G play on the same day.
Bring Group Winner is a set city (San Francisco) which we will know as at the 25 June and an opponent who we will know as at June 27 when the best 8 third placed teams are allocated at the completion of the Group Stage.
Being 3rd placed means that within the 495 possible combinations of 8 third place getters, there are 330 combinations where the Group D 3rd place getter qualifies for the Round of 32. Whoever finishes 3rd would only find out which of the 3 potential cities they play in on the 27th and may need to play on the 29th, which for Australia means potentially staying in SF after the Paraguay game and travelling on the 28th, or taking a punt and flying to the East Coast on the 26th if we finish 3rd and if necessary travelling again closer to the game.
The table for opponents for both the Group Winner and 3rd Place team are as follows
1D (vs 495 combos) 3rd D (vs 330 combos)
vs 3B (329, 66.5%) vs 1E BOSTON (212, 64.2%)
vs 3J (64, 12.9%) vs 1I NEW YORK (99, 30.0%)
vs 3I (52, 10.5%) vs 1K KC (19, 5.8%)
vs 3E (39, 7.9%)
vs 3F (11, 2.2%)
Top Seeds in Groups E, I and K are Germany, France and Portugal so if they top their groups they would be tough opposition.
Group B is the Canada Qatar Switzerland EUFA (Italy* top seeded for March playoffs) group and Group G is Belgium Iran Egypt NZ.
So a 67% chance of Canada/Qatar/Switzerland/? in San Francisco if first, a 100% chance of Belgium/Iran/Egypt/NZ in Dallas if second, and a 64% of Germany/Ecuador/Ivory Coast/Curacao in Boston as a top 8 ranked best 3rd placed team.
There are so many ifs buts and maybes but even with the expanded format finishing top 2 in our Group is super important to knowing the next city quickly and moving forward. For teams in Groups G-L finishing 3rd becomes a better (but still risky) safety net if the maths work in their favour.
Personally I would be ecstatic to move on regardless, so hopefully I can reference this in 6 months after we have wrapped up progression and are primed for a cup run for the ages.
