Wouldn't surprise me, that's how all other OHSAA team sport tournaments are done. The unfortunate part about that, is there are still some years where the two best teams reside in the South Region, which means the Regional Final could end up being the pseudo State Championship.
It wouldn't be the worst thing for the sport to have other representation in the title game, but it would stink to have the 2nd best team in the state be knocked off/out a week early. Matchups of two teams from the same region wasn't all that common in the 2010s, compared to the 2000s, however the past two state Finals have (X-Moe in '19, Elder-Moe in '21). There were even a couple of seasons without a GCLS rep in the Finals, in 2015 Darby defeated Beavercreek and in 2017 St Ignatius defeated Darby.
