Oak Hills and West Hi won't play because the conferences they are in are too big and not a common open date.
East Central has played LaSalle and Moeller, so I don't know why we have not played them. I know a ton of Alumni live out that way so I don't understand that.
Harrison is a whole different thing. The SWOC is shrinking. Ross and Edgewood are leaving. So the SWOC will be Harrison, Talawanda, Northwest, and Mt Health. Another 4 team conference. Which means 7 open dates. Harrison's schedule this is:
HARRISON
1@ Taylor
2@ East Central (IN)
3(H) Cincinnati Withrow
4(H) Cincinnati Western HIlls
5(H) Clinton-Massie
6(H) Campbell County (KY)
7@ Cincinnati Mount Healthy
8@ Talawanda
9(H) Cincinnati Northwest
10@ Wooster
So in future years they play their 3 league games. Then they keep Taylor and East Central. That still gives them 5 games they have to find. Elder would be logical. But I remember back in the early 2000 talking to Tom Gamble. He tried to get Elder vs Harrison in the showdown. Harrison refused.
Harrison won't be joining the GMC or ECC anytime soon. The FAVC broke up because those eastside schools thought the drive to Harrison and Oxford were too far. So I don't see the ECC wanting them. On top of that the GMC and ECC are both 10 team leagues with 9 game league schedule. If you add an 11th team, Who do they play when everyone else is already paired up? A league in Indiana might want them, but some sports don't match up. In Ohio boys tennis is a spring sport, Indiana it is a fall sport.
