Re phrase:: no mortal public high school will ever beat JCA
I mean, that's definitely hyperbole. I won't dispute that most of the lower end playoff qualifiers likely don't match up well with JC or many of the 5A traditional powers so there are plenty of lopsided examples as well. But there are lots of examples of good JC teams being tripped up by real good (and even some merely slightly above average) public school teams.
21...Semifinal close call escape over Richmond-Burton
19....Quarterfinal Loss to Mascoutah
12....Quarterfinal last play 2PC stop to hang on by 1 over LWW
10...Quarterfinal loss to Richwoods
06,,,,,Round 1 loss to Morris
05......Quarterfinal loss to Morris
03...Quarterfinal close call escape over Morris
02....2nd round close call escape over Riverside-Brookfield
01...Quarterfinal all timer over Riverside-Brookfield and close call escape over Morris in the final
00....Semifinal great last minute win over Pontiac and come from behind final win over Metamora
99....Quarterfinal Morris missed knocking JC off by a missed FG as time expired
2 of our better squads over the last 15 years lost to fairly nondescript public school teams. Then there were all those examples of close calls where just a few plays either way and JC finds themselves losing to a public school team.
