Heading into its bye week, Penn State's pursuit of Joe Paterno's 400th career win seemed a daunting task for the second half of this season.

The Nittany Lions had dropped two straight, including a Homecoming loss to Illinois, and were also riddled with injuries, especially on defense. At 3-3, getting the three more victories needed for the magic number appeared to be a challenge.

PSU has turned things around since its bye, picking up triumphs over Minnesota and Michigan to improve to 5-3 and within one win of Paterno's 400th Northwestern headed to Happy Valley this afternoon.

Today's game has a 3:36 p.m. kickoff and will be televised nationally by ABC/ESPN2.

The potential for Paterno reaching the milestone is only one of the themes running through this contest.

A PSU win would make Paterno the first Division I (BCS) coach to reach that elite circle. The two other NCAA coaches who have hit the 400 plateau are John Gagliardi, who is still coaching at Division III St. John's (Minnesota) and has 476 wins in 62 seasons, and the late Eddie Robinson, who had 408 in 56 years at Grambling.

Paterno downplayed the 400 win angle during his weekly press conference.

"I've been around for enough wins," he said at one point after several attempts were made to get him to comment on it. He did offer a little more insight later, noting that he has been around long enough to have piled up some wins during his 45 years on the Beaver Stadium sideline. He also said that it would be something to reflect on at a later time.

Regardless of when it happens, 400 win is achievement that happens rarely and will take a lifetime for others to reach. In today's big-time college coaching climate, who knows if it will ever happen again?

Another theme has been the rejuvenated Lion offense. Granted, PSU has faced two of the weaker defenses in the Big Ten the past two weeks in the Golden Gophers and Wolverines, but with the Lion defense giving up plenty of points and yards (Michigan QB Denard Robinson ran for 191 yards and 3 TDs and passed for 190 and a TD), the offense was up to the task.

The emergence of former walk-on QB Matt McGloin has become a storyline. The West Scranton product took over after Rob Bolden suffered an apparent concussion against Minnesota. While Bolden was cleared to play against Michigan, McGloin got the start (a first for a walk-on QB at PSU) and completed 17 of 28 passes for 250 yards, throwing for one TD and running for another.

Trying to diffuse a potential QB controversy, Paterno said both Bolden and McGloin would compete this week, and they are listed as co-starters on the PSU depth chart. Certainly, that gave Northwestern coach Pat Fitzgerald something else to think about in the Wildcats' preparations.

Reportedly, Bolden got to take snaps with the first team at practice. Paterno didn't commit to either QB during his radio show Thursday, although he suggested the Lions would look to use one instead of two QBs.

McGloin has been gracious during his rise, noting after the Minnesota game that the Lions were still Bolden's team.

The Lion attack has also gotten a boost from its rejuvenated ground game. Evan Royster finally became PSU's all-time leading rusher after running for 150 yards on a career-high 29 carries and scoring 2 TDs against Michigan. Royster passed Curt Warner and now has 3,518 to top the list, giving the "Blue Royster Cult" reason to cheer.

Northwestern (6-2) also has a Keystone State story of its own in QB Dan Persa.

The Bethlehem Liberty signcaller has completed 174 of 234 passes for 2,062 yards and 12 TDs against just three interceptions. He is also the Wildcats' leading rusher with 360 yards and 6 TDs, followed by freshman Mike Trumpy's 307 yards rushing.

"I know we looked at him (Persa) and for some reason or another, maybe we decided there was somebody else around that would be a little better, I don't know," said Paterno, when asked this week if PSU had recruited Persa.. "But he certainly has become one of the better quarterbacks, I think, in the country.

"He's a good student, good kid, hard worker. He's made some big plays for Northwestern and has been a big difference for them in a lot of games."

Persa, who left last week's 20-17 Northwestern win over Indiana with a concussion, is expected to play today.

Northwestern's top target is junior Jeremy Ebert, who leads the Big Ten in receiving yards per game and has caught 43 passes for 678 yards and 7 TDs.

Defensively, junior safety Brian Peters leads the Wildcats with 52 tackles, and junior cornerback Jordan Mabin has broken up eight passes. Nate Williams and Quentin Davis lead the linebackers. The defensive front is anchored by junior Vince Browne, who has six sacks.

The Wildcats own wins against Indiana, Vanderbilt (23-21), Illinois State (37-3), Rice (30-13), Central Michigan (30-25) and Minnesota (29-28). Their losses have come against Purdue (20-17) and Michigan State (35-27).

Penn State leads the series 10-3 and has won the last three in a row, including 34-13 last year in Evanston. This is the first time the Wildcats are visiting Beaver Stadium since 2006. The oddsmakers have PSU listed as a six-point favorite.

While the schools will be in different divisions when the Big Ten realigns next year, PSU and Northwestern are scheduled to meet the next two seasons.
