I don't know how you can tell, but would agree with your assessment on the groups if you are right.I think you have the two Slammers team mixed up. Looks to me like "Slammers AW" is actually Slammers AWCB 1 and "Slammers CB" is Slammers AWCB 2. I am not sure why AWCB 2 would be seeded ahead of AWCB 1 in the tournament, but that is the way it looks to me. If so, I would think CDA got a tougher draw than expected and San Diego Navy an easier path to win their group.
One interesting thing I just saw on the schedule is that groups J and K (the two groups of 3 instead of 4) actually play the three teams from the opposite group instead of just playing two games within their group. What if SD Surf A wins their first two games (including beating Anaheim) and is in position to win their group regardless of whether they win their 3rd game (which is against SD Surf B). Could they sandbag that last game in order to allow their sister team to win the group? Not saying they would, but it seems like a schedule like this makes it possible and I love a good conspiracy theory.
