D1 - NE 3 regional bids, NW 1 regional bid (central and SW have 6 each).
NE -> St. Ignatius is the favorite in the north and also statewide, as they return essentially everyone from a team that won the state title, despite being their weakest team in a long time. Medina and Brunswick are well positioned to take the other two regional spots. Massillon Jackson and Strongsville would be candidates to play spoiler
NW -> there are only three schools in D1 ... Perrysburg, Findlay, and Whitmer ... given that, let's just put Perrysburg in the sweet 16
D2 - NE 7 bids, NW 1 (central 5 and SW 3)
NW -> Toledo Start, Anthony Wayne, Sylvania Northview, Toledo St. John's, and Toledo St. Francis are the lone schools. The latter four schools will be battling for the spot, and it should be well-contested
NE -> Hoover, Hudson, and Walsh Jesuit are going to be the class of the area with the other four spots likely to be tightly contested
D3 - NE 6 bids, (NW 3, central 2, east 1, southeast 1, SW 3) ... this is the bottom of the old D1 along with the top half-plus of the old D2
NE -> I think it's going to be a very open battle for regional spots in this new division. Maybe US, Revere, and Twinsburg as a top three ... though I think this division is going to have the least gap between the regional advancers and the district semifinalists.
D4 - NE 4 bids (NW 3, central 2, SW 3, east 2, southeast 2) ... this is the back about half of old D2 along with the top portion of old D3
NE -> Bay and Cardinal Mooney look to be the class of this division. If Andrews Osborne does well in the international market like they did last year, they'll be right there with Bay (and Mooney). Going to be an interesting division though, as the old D2 teams will be seeing this as an opportunity for regional advancement with the bigger enrollment schools not standing in their way.
D5 - NE 5 bids (NW 3, central 1, east 1, SE 2, SW 4)
From a statewide perspective, you also have Worthington Christian up in DIV along with AOA, plus four other members of the final OSSCA top 15 for the old D3 at the end of last year. With SCD dropping down, they become the instant clear favorites for the state title.
NE -> AOA is out of the division and Beachwood is out of the division (regional finalist the last two years in old D3). United (with Candrea returning), Warren JFK, and South Range might be the three best teams in the geography for the fall.
