The Dallas Cowboys offense struggled mightily to move the ball during Saturday's practice, but they bounced back well on Sunday, as they were able to put points on the board against a stingy Dallas defense.

On a day where the offense was able to find a lot of success, Tony Pollard's touchdown run may have been the most impressive:

On this play, the Cowboys offense is in a shotgun formation with the tight end attached to the formation using 11 personnel (one running back, one tight end and three receivers) while the defense is using nickel personnel (four defensive linemen, two linebackers and five defensive backs).

Once the ball is snapped, the offense executes a split-zone concept, where Jason Witten comes across the formation to pick up the unblocked weak-side defensive end. The blocks from the offensive line and Witten are the biggest reason why this play was so successful, though Pollard certainly deserves his share of the credit as well.

Witten did an outstanding job of tracking the unblocked defensive end, who was knifing his way down the line of scrimmage to blow up Pollard's run before it started. That's a tough block to make, but Witten made it look easy.

Because Witten was coming across the formation to block the weak-side defensive end, it allowed Tyron Smith to quickly climb to the second level and secure a block on second-year stud Leighton Vander Esch, which is no easy task even for an elite offensive tackle such as Smith.

On top of that, Connor Williams and Travis Frederick's combination block on Antwaun Woods and Jaylon Smith gave Pollard a clear path to the end zone. Williams and Frederick did an excellent job of sealing Woods initially. With Woods sealed, Frederick was able to show off his elite second-level blocking ability, as he was able to climb to the second level to latch onto and control Smith, rendering him unable to rally to the ball carrier.

Nevertheless, Pollard also deserves credit for showing the patience to allow his blocks to develop, as he did a great job of pressing the front-side hole before executing an impressive jump cut to the back-side behind Witten's block. Because Pollard properly pressed the hole before cutting back, it gave the offensive line favorable angles to make blocks on Vander Esch and Smith at the second level.

From there, Pollard's burst took over, as he was able to accelerate through the alley in between Xavier Woods and Vander Esch, and into the end zone for the touchdown.

The Cowboys certainly miss Ezekiel Elliott, but his absence has enabled Pollard to gain valuable experience running behind the first-team offensive line, which should pay huge dividends later on this season.
