As good as the Packers' defensive front has been playing through the first quarter of the 2016 season, they've yet to encounter a true dual-threat at quarterback.

That drought will continue even after Sunday.

While the Cowboys' rookie sensation at the helm of their offense continues to take the league by storm, Dak Prescott has been impressing more with his arm than he has with his legs. Since being drafted in the fourth round and taking over for the injured franchise cornerstone in Tony Romo, Prescott has become a handful for opposing defensive coordinators to scheme for. But not with his 4.7 speed.

"He's poised," Packers' head coach Mike McCarthy said in a post-practice presser on Wednesday. "He doesn't take alot of chances which I think relates to his decision-making. His discipline has been good, and he seems very comfortable in what they're asking him to do. He's played very well."

Despite his high-speed capabilities, Prescott hasn't racked up as much yardage as one would typically think by glancing at his measurables. So far in 2016, he ranks twelfth among quarterbacks in rushing yards with just 61. He stations below Blake Bortles and Matthew Stafford, two quarterbacks the Packers' defense have acquainted themselves with this season. The common theme when watching Prescott is that he would fall into the category of a "mobile quarterback", but based off of a mere observation from his box score, that would be far from the truth. Especially when he's below Ryan Fitzpatrick and Andy Dalton in rushing yards.

Fortunately for us football poindexters, there's more to football than simple box scores. On film, Prescott has the mobility and precision when he does choose to take off and run. On a brighter note to go along with his measly 61 ground yards, he leads all quarterbacks with three rushing touchdowns. All of which have come from inside the opponents' 10-yard line. 

Safe to say, the Packers' defense as a whole — not just the domineering front seven, but the secondary as well, will need to be as efficient as can be come Sunday.

If Prescott manages to break containment and push the ball upfield, the closing speed that the linebackers have displayed in 2016, both inside and on the edge, should be capable of putting a quick end to endeavor. However, due to Prescott's adaptability to the pocket collapsing around him, which, if the first four games were any sort of blueprint, that is almost a guarantee, then he's more than viable to extend plays.

"I think when you counter that (Prescott's running ability) with an excellent run game, it's definitely heightened," McCarthy admitted. "The fact that they're running the football, the action-passing game off of the run game and more importantly the quarterback movement packages in the action game are a very big challenge for our defense."

Much like Green Bay's own Aaron Rodgers has made a living doing for most of his career, Prescott doing so will not only buy time for his receivers to find open space, but also create a break-down in coverage. With a secondary rolling without it's starting cornerback and possibly — no word yet, without Damarious Randall, that could create a very, very drastic scenario that favors the visiting team through four quarters.

Many are hanging their hats on the defensive backs occupying the Packers' secondary being "perfectly fine" based off of their one acceptable performance in the recent Sunday night affair. Take said hats off the hat rack and tip each and every one for Joe Whitt Jr. and Darren Perry, whose respective cornerbacks and safeties unit performed beyond expectations against the Giants. Nevertheless, it's a small sampling size to gather all of your eggs into one basket over.

Dallas' top target in Dez Bryant being available for Sunday is still in the clouds as well, but would add another elite-tier receiver the likes of which a young secondary would have to attempt to lock down. At the moment, the Cowboys' offense is looking like something close to a powerhouse, and with the league-leading rusher in the backfield — another rookie, a laborious task awaits the Packers.
