What we learned on the gridiron this weekend is that while the North Suburban Conference Lake Division plays a pretty good brand of football, it’s just not the same as what they’re doing in the Chicago Catholic League’s Blue Division. Loyola Academy’s 21-7 win over Warren High on Saturday in the Round of 16 of the IHSA Class 8A playoffs meant that the Catholic League’s elite division’s four playoff qualifiers went a combined 8-0 over the first two weekends of postseason play.
