The defensive struggles for the Warren County High School football team were well documented last year. The Pioneers gave up 41.8 points per game last year and opponents averaged over 350 yards, leaving Warren County in catch-up mode nearly every Friday.Knowing improvement had to start with the stop unit, Warren County has spent lots of time since the end of last season trying to develop defensively.Defensive coordinator Chris Johnson, who also serves as defensive backs coach, and linebackers coach Paul Martin each believe the Pioneers will be much more potent this season.Returning most of the secondary helped coach Johnson, while coach Martin inherited a hungry group of young linebackers who have stepped up to the challenge in the preseason.Coach Johnson hasn’t changed the schemes on defense. Instead, the coach focused on fine tuning some portions of the defense as his starting secondary has figured out the system.“We have an experienced bunch in the secondary and we look better than we’ve ever looked,” said Johnson.
