Well this is odd. Snider is being placed back in 6A due to the changes. Apparently, the IHSAA is going to redo sectional alignments. This article does not say who else is affected, but does say more schools than just Snider will be impacted.

This has nothing to do with New Pal. You just seem to be dismissing the quality of Columbus East, Cathedral and Roncalli who will no longer be in 5A and thinking the additions of Dwenger and Snider balance that out, that's what is comical.
