Outside of LaSalle, Elder rarely plays DII or lower Ohio teams. As I said, Elder will only consider it if they believe the opponent will give them a bunch of Harbin points, which is why they agreed to play Withrow, who won 9 games last year. That's why they were playing Winton Woods, but when they got beat a couple of times, they stopped scheduling them.
Elder and GCL-S is about prestige and brand. They bring in these out of state powers because it's what is cool.....look, we are doing something that nobody else around is doing, playing teams from Michigan, Pennsylvania, Florida, etc. It hypes the fanbase and the donors. The donors don't want to see Elder beat up on Harrison. Or God forbid, Harrison has a fluke and somehow wins, then the sky would be falling.
Go ahead and do your research, and you will see that I'm right, it's out of state teams, or a D2 "Harbin Cow" that Elder is confident they can beat. I'm willing to bet it would be really easy to schedule Hoban, Massillon, Steubenville, Ursuline, Watterson with 1 phone call. Heck, they could probably get McNick or Alter pretty easily. Let's not forget about East Central, or any other teams in NKY that I'm sure would love to cross the river to try to hang with the big boys.
The point I'm making is if you talk to enough ADs, they all say how difficult it is to work anything out with any of the GCL-S schools. I really believe that the GCL "Scheduling problems" are of their own doing. With how easy it is to make the playoffs now, no way all these schools with open weeks are ducking anyone anymore.
