I wonder with the Berea announcement, could Asbury soon be joining as well to make it an even 12?
That was my first thought as well, particularly since it adds another Kentucky school to the HCAC.
An even dozen would allow the HCAC to realign itself into two balanced divisions.
A couple things jump out to me here.
If you're Defiance you'd be looking at a situation in which your conference has expanded in/around/beyond what was already your longest trip. If it comes to it, maybe a North/South split of divisions keeps this from being a major concern.
If you're Centre, you're looking at a situation where every other Lexington, KY area DIII is in the HCAC.
