Northwestern coach David Braun called last week’s lopsided loss at Iowa “an embarrassing performance.”With bowl eligibility still a mathematical possibility, the Wildcats will look to move on when they visit another struggling Big Ten team, Purdue, on Saturday in West Lafayette, Ind.Simply moving the ball should go a long way to that end. Northwestern (3-5, 1-4) gained only 163 yards of offense against Iowa, including 43 rushing yards on 24 carries, in the 40-14 defeat.”To run the ball and meet our standard, in some regards, we have to overachieve,” Braun said. “… Let’s get in the foxhole, let’s go attack this and find a way to get this done.”Cam Porter (13 carries, 50 yards) was Northwestern’s top rusher. The Wildcats will stay with Jack Lausch at quarterback despite recent struggles that included a pair of interceptions at Iowa. Northwestern scored its lone touchdowns by interception and punt return.Purdue (1-6, 0-4) enters on a six-game losing streak that continued with a 35-0 home loss to visiting No. 2 Oregon on Oct. 18. Purdue has been idle since then.Braun was quick to note that the same Boilermakers who struggled to fend off the Ducks pushed then-No. 23 Illinois to the brink in a 50-49 overtime loss the week before the Oregon game.”We can’t allow stats or a record to lull us to sleep,” Braun said. “That’s a very talented football team.”Purdue passed for a mere 93 yards against the Ducks with Hudson Card still in the concussion protocol. In his second career start, Ryan Browne was 9-for-19 through the air with an interception. He added 48 rushing yards.Reggie Love III paced the Boilermakers’ ground game with 93 yards on 11 carries as Purdue ran for 208 yards.
