There was a committee a few years back that the IHSAA formed to look into this changing the sectionals, I think it had around16-20 guys on it. The IHSAA didn't really listen to the committee at all. I went there as a Fort Wayne Semi-state representative fully expecting something like this to come from the recommendations, but that was not the direction the IHSAA seemed to want to go at that time.
What I mean by that is there wasn't a push to make big changes like what your proposing above. Its hard to explain with out a map, but there would need to be a lot of shuffling to send those Northern Indy schools to Fort Wayne. I think some proposed Penn head to Fort Wayne, but again the IHSAA didn't listen to the committee very much.
I thought there might be discussion of sending whole sectionals to different semi-states, but that was not on the table at all at that time. It was literally just a team or two, that might move to a neighboring sectional that was recommended.
Another thing on this topic, has anyone done the numbers on placers by semi-state? We did a quick count on Saturday and I had more placers coming from Fort Wayne than East Chicago (Again I could be wrong on this). Those two have been the worst in terms of placers most years recently, so I'm not sure if taking a better team from there is really the best option to change Fort Wayne's results.
