I'm not as personally close to the game as I once was, but most years you could figure on 2-3 SCAL teams having the potential to reach a regional final. This year Riverside is off to a quick start, and Troy Christian is fairly strong as well and faces Russia in a couple weeks. Does the Wapak district go to the south west regional this year? If so there is probably a MAC school that could reach the finals as well.
According to this link, the Wapak district will once again go north to BGSU. The last time the Wapak district went south was 2019 when St Henry made it to state out of the SW district and Crestview made it out of the NW district. There have been several years where the Elida district winner goes to state through BGSU along with the Wapak district winner going to state through the SW regional. You can see how physically close some of these schools are, where if you send Wapak north, you don't get teams that are as close.
2019 - St Henry (SW) Crestview (NW)
2018 - Marion (SW) Pandora Gilboa (NW)
2017 - Lima Perry (SW) Del St John’s (NW)
2009 - Ada (SW) Kalida (NW)
2008 - New Knoxville (SW) Wayne Trace (NW)
2005 - Minster (SW) Continental (NW)
2003 - Marion (SW) Crestview (NW)
2000 - St Henry (SW) Fort Jennings (NW)
Not a conspiracy theorist, but I do wonder. If you take a 1-2 county radius around Lima, there are a ton of good basketball schools from the PCL, NWC, MAC, and SCAL. In 2021 you had Botkins vs Columbus Grove for the state finals. Now I do realize Botkins always goes SW, but still relatively close. There are just some years where St Henry, Wayne Trace, or LCC have jumped between D-3 and D-4 and that can really impact who goes to state, especially if they all happen to fall into D-4.
