TV/radio:

11 a.m. Saturday; ESPN, WGN-AM 720, WNUR-FM 89.3.

Line:

Penn State by 21/2.

Records:

Northwestern 5-0,1-0 Big Ten; Penn State 3-2, 1-0.

Last meeting:

Penn State won 34-24 on Oct. 22, 2011, in Evanston.

ON THE OFFENSIVE:

The last time the Wildcats faced a Ted Roof-coordinated defense (the 2010 Outback Bowl against Auburn), Mike Kafka threw five picks — but also completed 47 of 78 passes for 532 yards.

GETTING DEFENSIVE:

Penn State’s Matt McGloin has torched NU’s defense, completing 63.6 percent with six touchdowns and no interceptions in two starts. Receiver Allen Robinson is dangerous.

THE NUMBER:

1962. The Wildcats are gunning for their first 6-0 start in 50 years.

THE TALK:

Will this be a letdown game for Penn State after crushing Illinois, the team some believe tried to poach its players?

TEDDY GREENSTEIN’S PICK:

NU’s Kain Colter-Trevor Siemian combo will produce just enough to gut this one out.

Northwestern 31, Penn State 28
