Purdue’s defense gave up 389 yards against Northwestern last week.
That’s the second-highest yardage total of the season.
But the Boilermakers still may have played their best defensive game.
Purdue had a season-high five sacks, limited Northwestern dual-threat quarterback Dan Persa to 24 rushing yards on 20 carries and forced a season-high six punts.
The challenge now is to continue to move forward.
“There are some things we could do a lot better,” coach Danny Hope said. “Coming into the game (last) Saturday, we challenged a lot of guys on our football team to take a look at their game. … The light came on in some aspects for a lot of our players. The light came on for some of our defensive linemen. The light came on for some of our linebackers.
“But it’s not beaming bright. It is flickering a little. We have to keep doing it. We have to show up and get ready to take another step as a football team because the competition gets tougher every week.”
