Well, I am not completely sure on how all of this is going to work, but - they can all still play each other during the season - and wouldn't this make it where they could end up facing each other further down the road in the playoffs? I mean, in the same district there would be less of a chance of them playing each other deep in region and/or substate, right? So, I would think they could still play each other in season - it just wouldn't be a district game, and it would be interesting deeper in the playoffs if they faced each other.
I know it is not ideal, but no classification is completely perfect.
Trenton will now most likely not be playing Milan in football, and that has been a county rivalry forever.
