Coatesville vs. Unionville will not be that interesting unless Ortega isn't playing...they'll roll. I do think AG vs. Rustin could be an interesting game.
Not sure what the WCASD athletic department has to do with Great Valley and Oxford? League mandated crossover games 4 years ago. All principals and AD's voted on the changes to the divisions & the mandatory "Big 4" game (DWest, DEast, Coatesville, Avon Grove) for the smaller schools. If other schools weren't happy, they could've out voted it 11-3. If anyone should complain it would be CV, DWest, and DEast having to play teams they'll mercy rule in the middle of the season. I think next year they'll pick up some Del-Val games like Penn Wood, Academy Park, and Chester. Not sure those will be that much better....
Anyway, Ches-Mont is proving to be the strongest league in SEPA across 6A and 5A. 3 legit contenders in 6A for D1 title, WC East looks to be for real in 5A, Kennett looks like a sleeper, Unionville and Rustin are not as dominant but nobody will want to play them in the playoffs.
