I am not so much chagrined as concerned.
Indiana wrestling participation per NFHS:
2015-2016: 7156
2016-2017: 6810
2017-2018: 6675
2018-2019: 6622
US wrestling participation per NHFS:
2015-2016: 264,149
2016-2017: 259,391
2017-2018: 262,126
2018-2019: 268,565
Last three years, HS wrestling in the US is getting more popular, while HS wrestling in Indiana is getting less popular.
Even the year there was a drop (15/16 to 16/17) both nationally and in IN, national numbers decreased by about 1.8%, while Indiana number decreased 4.8%, which is a pretty stark difference. Again, I don't know if class wrestling is the magic bullet, but it is the one big thing that we don't do that nearly the entire rest of the country does do.
