I know of at least 2 opponents that have canceled games with WB, either with at least one game remaining on the contract or before the series began. Another didn't want to renew after this season.
Next year WB plays Canfield (7 playoff appearances since 2015), New Philadelphia (8), Chaney (2), Struthers (6) and Howland (2). That's four D3s and a really good D4. Howland is going to be on the schedule for the foreseeable future.
I'm not sure what else y'all want them do. I know Massillon always has some open dates.
