Marengo coach Paul Forsythe was proud of his players for battling in the elements, which made it hard for either team to hold onto the ball in the third and fourth quarters.
Marengo was 2-7 last year. It became playoff eligible with Friday night's win.
"Last year, they got a running clock on us," Forsythe said of last year's game against the Skyhawks. "The strides we've made in the last year are huge. I'm just excited for our kids to experience that. Being 4-0 in conference is pretty big, and we've put ourselves in a good spot."
Schirmer finished with 137 yards rushing on 26 attempts and a 15-yard score, Knaak went 10-of-20 passing with 102 yards and ran the ball 16 times for 66 yards, Shepard had two catches for 43 yards, and Cole Davis had three grabs for 30 yards.
Johnsburg grabbed a 7-0 lead in the first on a Alec Smith 27-yard touchdown pass to Jonny Preston. The Skyhawks wouldn't score again until Linkletter's return for a touchdown.
"They executed more plays than we did in the conditions, and we fumbled the ball a couple times on snaps, and we weren't able to move the ball offensively at all," Johnsburg coach Sam Lesniak said. "We didn't have a very good week in practice, and it showed."
