Just to clarify, in Michigan, it was the school leaders, superintendents, coaches, players and parents who put the pressure on both the MHSAA and Governor to make a decision on Fall sports. Throughout August, the Governor's office was saying it was up to the MHSAA to figure out Fall sports, while in turn the MHSAA said its hands were tied without an executive order from the Governor. The later has been widely proven to be BS.
In the end, the Governor issued an EO, which broke the dam and reinstated Fall sports.
As for Illinois, the pressure needs to be applied by all forces to JB, in my view. This should include the IHSA.
A huge rally in Springfield would be helpful, but as Edgy points out, that's a 3 hour drive from the city and burbs.
