I think this makes it much easier for another Wilmo I8 title
As far as two smaller conferences, it makes perfect sense. In the 10 team conference situation every team within the conference would not get a chance to play each other since some of the teams have non-con games on their schedule.
Week 2 could be the overall I-8 championship...Wilmo and Manteno are the only schools playing a full round-robin this year, so this could be the game. Of course, not as cool as '14 & '15, when they rolled into week 9 as undefeated small & large champions...
Two divisions of 5 is like kissing your sister...there is no benefit, no automatic bid; unless Wilmo wants to keep it's undefeated conference streak alive for another year...
Herscher & Wilmo haven't played since 2015 when Herscher went to the large division - I remember Stuart killing the Cats' secondary in '15 as the 6'8" monster kept getting huge catches in a too late comeback attempt while the Cats just completely shut down the Tigers rushing attack...Soph game in '14, Herscher sophs only had three decent plays - all long TD passes to Stuart.
