Warren scored two touchdowns early against New Trier Friday night, but the Blue Devils needed two fourth-quarter turnovers to hold off a Trevian rally in Northfield.
Ryan Sweeney and Johnathan Whitfield each picked off Frank Nicholas pass attempts before Warren added a late rushing score to preserve a 21-6 victory.
The Blue Devils (1-1) pieced together a seven play drive toward the end of the first quarter, scoring on a 30-yard pass from Adam Reuss to Connor Iwema, giving them a 7-0 lead following a Matt Massong PAT kick.
New Trier (0-2) answered immediately with a drive that lasted eight plays and culminated with a Grant Amick 35-yard field goal on the first play of the second quarter, trimming the lead to 7-3.
The momentum did not last long for the Trevians, though, as Warren answered on the next play from scrimmage.
Davonte Willcox responded with a 72-yard TD scamper that gave the Blue Devils a 14-3 lead after the Massong PAT kick, less than one minute into the second period.
Willcox also added Warren’s final score, breaking off a 29-yard scoring run with just over a minute left in the game. The senior collected 166 yards on just 14 carries.
“I knew it was going to be tough (scoring), but I was prepared for it,” Willcox said. “When my time came, I made it happen.
“I put that all on the linemen, all the credit goes to them. They work their butts off in practice all week. They do their job, and when I get that hole, I go all the way.”
Amick added a 23-yard field goal with just seven ticks left before half-time, in addition to having a 23-yard attempt blocked toward the end of the third quarter.
Despite back-to-back picks, Nicholas was 13-of-23 for 129 yards, including five straight completions to start the game. He also rushed for 31 yards, while Michael Thomas led the New Trier with 71 yards on 14 carries.
