Overview

The Cowboys did not play great defense in 2023, but they were good. They allowed the fifth-fewest yards through the air, had the fourth-lowest completion percentage, and were tenth in plays of 20+ yards. Dallas ranked eighth with 17 interceptions, and their 46 sacks were more than respectable. The run defense was a little less successful but was in the top half of the league in all the main categories. They gave up the sixteenth most yards, ranked fifteenth in yards per carry, and were eleventh in runs of 20+. The Cowboys tied for twelfth with 27 turnovers while, in the category most significant to wins and losses, they surrendered the fifth-fewest points.

The organization must have been content with last year's performance, at least from a personnel perspective. The team's most important change was at defensive coordinator, where Mike Zimmer will take over. The rest of their offseason attention to that side of the ball amounts to a second-round edge defender and a pair of third-day guys in the draft, with one significant free-agent move.

The good news for the organization is that the starting unit returns virtually intact. The bad news is their depth was depleted in free agency. That could be a plus for IDP managers with more time on the field for some players, but it could also leave the Cowboys vulnerable. The move to Zimmer could also help on the IDP side. From his first stint in Dallas to six seasons as the Bengals DC and eight as the head coach in Minnesota, Zimmer's defenses have been strong and have given us a slew of quality fantasy options.

Defensive Linemen

Micah Parsons is the face of the Dallas defense, or at least he is the most recognizable name. He is a rare example of a young pass rusher who needed no transition time between college and the NFL. As a rookie in 2021, Parsons split time between off-ball linebacker and edge. The dual role helped him rack up 64 tackles, 19 assists, 13 sacks, and 3 forced fumbles. His tackle numbers slipped in year two when Parsons saw less action at linebacker, and they are probably not coming back. His 2022 numbers of 42-23-13 with 6 turnovers were good enough for a seventh-place finish among edge defenders.

His solo stops were down a little last year, but the combined tackles were nearly equal. At 36-28-14 with a pair of turnovers, Parsons was back in the top ten. We may never see another 50 solo tackle seasons from him, but Parsons is 25 years old and has just entered the prime of his career. He is just short of elite-tier consideration but is a safe bet for another top-ten finish.  

DeMarcus Lawrence is entering season eleven with the Cowboys and has been a starter since 2015. He was a solid, three-down defensive end for much of his career, but his role has evolved recently. There was a point when it looked like Lawrence might become one of the elite. His best season was in 2017, when Lawrence put up 58 combined tackles, 15 sacks, and 6 takeaways. He followed that with a mark of 42-21-10 and 4 more turnovers in 2018. Unfortunately, Lawrence has no more than six sacks in any season since.

Over the past few years, the Cowboys have been using an edge rotation that has Lawrence working on early downs but heading to the sideline in a lot of passing situations. That approach limited him to 612 plays in 2023, resulting in the lowest production of his career in a non-injury season. Dorance Armstrong and Donte Fowler are gone, but don't count on Lawrence getting significantly more playing time. The plan is to give Sam Williams more playing time and have rookie second-round pick Marshawn Kneeland step into the rotation as well.

Lawrence is 32 years old and in the final year of his contract. That could mean Williams and Kneeland are auditioning to be next year's starter. Williams was the team's second-round pick in 2022. He has seen limited action over his two seasons. Williams has 576 snaps as a pro, totaling 30-18-8 with 5 turnovers. With a bigger role, he could become an IDP factor.

Kneeland comes out of college with a similar scouting report to Williams. He has a great motor and the physical tools to become a good starter but needs more sand in his pants to hold up as a point-of-attack defender versus the run. Kneeland has strong hands and gains separation to make plays but can be pushed around at times. He is bigger than Williams and has the frame to add more muscle, so with a year or two of experience and weight room work, Kneeland could make a good three-down starter.

His college production was not exactly impressive. As a three-year starter for Western Michigan, Kneeland totaled 126 combined stops with 13 sacks and 3 forced fumbles in 32 games. Chances are, he will be worked in on passing downs in 2024. There may not be much short-term value, but Kneeland is a good taxi candidate for dynasty managers.  

The Cowboys rotated five players at the tackle positions last year. Osa Odighizuwa logged the most playing time at 647 snaps, while no one else played more than 351. Odighizuwa was also the closest thing to an IDP contributor among this group. It was an odd season for him, though. He came out of the gate on fire with six tackles and three sacks in the first two games. Then came a face plant that saw Odighizuwa fail to record another sack all season. He continued to make some contributions in the tackle columns, but that eventually dried up also. He recorded no solo stops over the final four games.

The virtual vanishing act might be attributed to a combination of things. There is speculation that some of the Dallas defenders wore down late in the year. Some blame the scheme, and then there is the shoulder injury that Odighizuwa has been nursing in the off-season.

With a final mark of 26-20-3, Odighizuwa ranked 39th among interior linemen last year. Well out of the realm of usefulness to IDP managers. However, he was sitting at number 25 heading into week fourteen. He is a talented player who holds up well versus the run and is capable of better numbers as a pass rusher. The move to Mike Zimmer as coordinator might be the spark that lights the fire. Zimmer has given us some highly productive interior linemen over the years, and he's not afraid to keep his best players on the field.

The Cowboys used a first-round pick on Mazi Smith last year. He was not much of a factor as a rookie, at least partly due to a bum shoulder that was surgically repaired after the season. With Neville Gallimore and Johnathan Hankins gone, the team will rely heavily on the second-year man to step up.  

Smith is quick and athletic for a man who is six foot three and 337 pounds, but he is going to see a lot of double teams as the one-technique tackle. This will not be new to him after dealing with the same thing as a two-year starter at Michigan. Like many that play the position, Smith's contributions on the field are not likely to show up big on the stat sheet. In 28 games for the Wolverines, he averaged barely over three combined tackles per game and had half a sack.
