The GCL-Coed is facing some issues, they are about to be down to 5 schools with Purcell-Marion and Roger Bacon joining the MVC leaving McNick in a precarious spot as being an hour plus on a bus from their closest league opponent, so that leaves the COEd with Fenwick, Alter, Carroll, Badin, and CJ as a five team conference I don't think Fenwick is that big of a stretch they used to be in a conference with Franklin, Edgewood, Monroe and Talawanda.
Big: All D2 and D3 teams
Edgewood
Talawanda
Wilmington
Franklin
Monroe
Ross
Bellbrook
Fenwick
Small: All D4 and D5 teams
Clinton Massie
Oakwood
Valley View
Eaton
Waynesville
Carlisle
Brookville
Madison
Would not have to play any crossovers and allows for three non league games, could play crossovers if you'd like in weeks 1-3 would make for a heck of a conference in my opinion.
