Don’t look now, but Arkansas’ front seven is good. Really good.

Defensive coordinator Robb Smith has built a devastating front seven that has gotten stronger as the season has progressed, suffocating opposing offenses.

The Razorbacks rank fourth in the SEC in rush defense, allowing 126.7 yards per game, fourth in opponent first downs and third in red zone defense.

In last week’s win over LSU, Arkansas allowed just 123 total yards of offense. The Bayou Bengals’ power run game totaled just 36 rushing yards on 32 attempts. That’s 1.1 yard per carry.

The Hogs allowed just 66 rushing yards to Alabama. Mississippi State’s vaunted rushing attack amassed just 128 yards on the ground against the Razorbacks.

The front seven has had some lapses this season. Arkansas allowed 207 yards on the ground to Georgia. Auburn rushed for 302 yards in the season opener.

But the front seven — led by Martrell Spaight, Trey Flowers and Darius Philon — is beginning to hit its stride, the effects of which we saw in the win over LSU last week.

Arkansas recorded six tackles for loss and four sacks on Saturday night, and wreaked havoc on LSU quarterback Anthony Jennings all night. Perhaps the defining play of the night was a late forced fumble by Spaight that sealed the win for the Hogs.

Smith boasts a veteran defensive front, but also one with depth.

The Razorbacks start four sophomores and three seniors on their front seven, and will lose a lot of production with the departures of Trey Flowers, Braylon Mitchell and Martrell Spaight.

DeMarcus Hodge, Deatrich Wise, Jr. and Brandon Lewis have all gotten significant minutes this season and should provide a boost — along with returners Taiwan Johnson, Darius Philon, Brooks Ellis and JaMichael Winston — for Smith’s defense heading into next season.

What’s most scary, perhaps, is that the Razorbacks’ are this good along the defensive front in Smith’s first year at the helm. Chris Ash left after last season to become the defensive coordinator at Ohio State.

The 38-year-old Smith had success at Rutgers, leading a defense that ranked fourth in the NCAA in scoring defense in 2012. Smith has taken an Arkansas defensive unit that had some embarrassing performances last season and is turning it into one of the more underrated units in the country.

The Razorbacks will have another chance to showcase its ability on Saturday afternoon against Ole Miss. Left tackle Laremy Tunsil is expected to return for an Ole Miss offensive line that has been makeshift in recent weeks.

That’s good, because if its past two outings are any indication, Arkansas’ front seven will spend plenty of time in the backfield on Saturday afternoon.
