Rotating district match ups is a good idea, I just think it can be improved.
I agree. I think we should draw the match ups for each age division after Districts. Example: 8U D2 vs. D4, 10U D2 vs. D1, 12U D2 vs. D3, 14U D3 vs. D4, and High School D4 vs. D1. These could be drawn out of a hat after Districts to lessen the temptation of positioning for a better spot in the bracket.
I agree, there is still some positioning going on in districts that can't be avoided until no one knows what districts they will face. Then everyone should go to win without trying to get the "better side" of the bracket.
