The 2005 Porter’s Chapel Academy Eagles posted one of the most dominating defensive seasons of the 21st century, on any level — they only allowed 10 points and no offensive touchdowns in their first 11 games. The only touchdown allowed was on a fumbled kickoff return against Tri-County in their eighth game of the season.

PCA’s season ended with a 20-13 loss to Lee Academy (Ark.) in the MAIS Class A semifinals.

St. Aloysius, meanwhile, had a similarly dominant season way back in 1938. The second team coached by the legendary Joe Balzli outscored its opponents 262-12 and finished the season with five consecutive shutouts.

Only two of nine opponents scored as the Flashes went a perfect 9-0. The nine consecutive wins were part of a 20-game streak that spanned the 1937-40 seasons, and included another undefeated season in 1939.
