ECNL always announces changes in their playoff formats in advance, not during a tournament (weather is the exception).
The system is done similar to college playoff brackets, where there is always a chance of a cinderella winning it all.
The final 8 is set, rather than final 4 because it makes more sense for college scouts and because it's done over 2 events rather than more.
No one is placed at a disadvantage because teams 2,3,4 of the groups are done randomly and the southwest didn't have to play each other during group play, allowing many southwest teams to win their groups and qualify for the round of 16.
It is frustrating when you have to travel across the country and play someone in your backyard but when you're in the conference in the country, this might happen at playoffs and championship series.
Very proud of the performances by southwest teams in playoffs, even the ones that didn't make it to Virginia.
Aren't we all lucky that we get to play extremely great teams multiple times throughout league play? The challenging season better prepares the teams for playoffs.
