While watching tomorrow's game, stare down the line of scrimmage when Wisconsin is on defense.

There will be four men -- all as strong, all as fast and all as savvy as they are talented.

Then, see them explode off the ball as it's snapped. Notice, they stay right in their pass rushing lanes, making a beeline for the backfield.

You'll see it's a straight line, too. They don't stunt or twist or necessarily try to confuse the offensive line with blitz packages. They just aren't fancy like that.

But when you're as good as Wisconsin's defensive line, you don't have to be fancy.

"They're pretty straightforward," Penn State offensive tackle Andrew Richardson said. "I've seen on tape that their coaches think they are talented enough that they don't need stunts and twists to get free, they just get straight off the ball."

There is no wasted effort. The Wisconsin defensive linemen just -- plainly and simply -- get after it. Which has worked well so far, as evidenced by the five sacks and 12 tackles for a loss they have already compiled through three games.

And the fact that their production rarely requires the aid of a blitz could be an even scarier thought for the Penn State offense.

"They can get pressure without blitzing, just with four down lineman," Penn State utility player Michael Robinson said. "They can keep a lot of guys back to help with the pass. They stop the run with just their front four."

If a front four can get the job done by itself, as Wisconsin's D-line does, things become much more complicated for the opposing offense. Suddenly, guys like the Badgers All-Big Ten safety Jim Leonhard don't have to concern themselves with run support. Instead, they're poised to ball-hawk for interception opportunities. In fact, that's how Leonhard has gotten most of his 18-career picks.

As Penn State's Mr. Everything on offense, Robinson will be troubled by this fact everywhere he goes -- wide receiver, quarterback or even running back. And he knows it.

"Their front four is one of the best front fours I've ever seen," Robinson said.

Several of the Penn State offensive players echoed that statement this week. And looking at its personnel seems to confirm that.

The Wisconsin down lineman with the most star-power is senior Anttaj Hawthorne, an agile run-stopper who was lauded as a preseason All-American by several national publications including Lindy's and The Sporting News. The Connecticut native, who was recruited by Penn State out of high school, had 20 tackles for a loss last season.

But the Wisconsin offensive lineman who has been making the most waves recently is Erasmus James, who is the most recent Big Ten defensive player of the week. Last week, in the Badgers' 9-7 win against Arizona, James had five tackles, two sacks for minus-25 yards and a forced fumble. Though the Penn State offensive line has done an admirable job in pass protection thus far, this could be its toughest assignment of the season.

"I've been looking at James [on film] all week, and he's pretty talented," Richardson said. "I'm going to have to be on top of my game."

Though not as publicized, Wisconsin's other two defensive linemen -- senior defensive tackle Jason Jefferson and senior defensive end Jonathon Welsh -- are loaded with experience and not that far behind Hawthorne and James in terms of ability.

Of course, singling out any of these talented players isn't necessary anyway.

Because all four work together in their own simplistic way to form a dominant unit.

A unit you need to keep your eye tomorrow.
