The Dallas Cowboys’ defensive problems are so obvious that they’re already shaping trade speculation before the deadline.
Through six games, Dallas has been one of the league’s weakest units on that side of the ball. The Cowboys are 23rd against the pass, last in the NFL against the run, and are allowing the eighth-most points per game.
The issues are spread across the defense, but the pass rush has been especially thin. Dallas has only eight sacks, and three of them came in Week 6.
Even worse for the Cowboys, just 2.5 of those sacks have come from edge rushers.
That’s why any realistic deadline conversation has to start there.
In a Sports Illustrated roundup of 15 players who could be moved before the Nov. 10 trade deadline, Matt Verderame listed Miami Dolphins defensive lineman Zach Sieler and named Dallas as a possible destination.
"Sieler is an interesting trade chip. On one hand, he’s already 31 and he’s signed through 2029 with base salaries of $12.6 million, $15.4 million and $16.2 million, respectively. In short, he’s not cheap to acquire," Verderame wrote.
"Conversely, none of that money is guaranteed, and he could be traded for and then released for no dead cap charge if things don’t work out. For Miami, it makes sense to move on, but what’s the right price point? Since 2023, Sieler has 27.5 sacks."
Sieler has been productive as a pass-rusher, piling up 27.5 sacks since 2023 and posting 10 sacks in a season twice over that stretch. He has two sacks this year, which would be tied for the team lead, and he had 5.5 in 2025.
Still, the fit is far from perfect. Sieler is a 6-foot-6, 300-pound interior lineman. He has lined up at edge in a 4-3 look, but Dallas operates out of a 3-4, where the Cowboys would need an outside linebacker rather than what Sieler is.
If Dallas completely misses on more natural outside linebacker targets, then maybe Sieler becomes the fallback option. Even then, Miami would likely have to absorb a significant chunk of the money for the Cowboys to seriously consider it.
He would be a clear upgrade over Otito Ogbonnia as a pass-rusher and has long been a strong run defender, though his work against the run has been rough this season. His Pro Football Focus grade sits at 31.6.
A defensive front with Sieler, Kenny Clark and Quinnen Williams would look imposing on paper and could give Dallas the pass-rush jolt it badly needs. But even with that in mind, it’s hard to picture Sieler actually landing in Dallas unless something drastic happens to Williams or Clark.

Cowboys Face A George Pickens Decision That Could Shape Their Season
George Pickens has quickly become one of the biggest decisions sitting in front of the Cowboys as they try to steady a season that has already gotten away from them at 2-4. He is on the franchise tag in 2026, and while he wants a long-term deal, Dallas has not pushed an extension forward, leaving the front office to balance present-day production against a future that could get messy fast.
For a team still trying to keep its season alive, the temptation is obvious: hold onto a talent like Pickens and hope he helps fuel a turnaround. But if no agreement comes together, the Cowboys also have to reckon with the possibility of losing him in free agency without getting anything back, which is why his name is already surfacing in trade talk before the deadline even arrives.

Dak Prescott's Rough Stretch Is Becoming A Real Cowboys Problem
Two weeks into the 2026 season, Dak Prescotts slump is becoming more than a bad run of games for the Cowboys, it is starting to shape the way their season is being discussed. The veteran quarterback has struggled to match his usual standard, and the latest warning sign came against Green Bay, where his decision-making and execution broke down under pressure and the offense never found a rhythm.
For a Dallas team still hanging around in the NFC East despite a 2-4 record, that puts even more weight on Prescott finding his footing quickly. The Cowboys do not have the luxury of waiting long for clean drives and steadier throws, especially with the defense doing enough to keep games within reach. The concern now is not just one poor outing, but whether this stretch has turned into a real problem for a team trying to stay in the division race. [Read more 🡒]
Cowboys Finally Showed Defensive Life After The Micah Parsons Trade
The Cowboys did not leave Green Bay with a win in Week 6, but they did leave with a little more defensive life than they had shown in recent weeks. Against Micah Parsons and his new Packers teammates, Dallas managed three sacks, its best pass-rush output in some time, and for a defense that had been searching for any sign of a reset, that mattered.
Micah Parsons presence on the other sideline gave the game an extra layer, but the bigger takeaway for Dallas was the way the front began to look more active and disruptive. Even in defeat, the pass rush offered a glimpse of what this defense might still be able to become after a rocky stretch, which is at least something for the Cowboys to carry into the next part of the schedule.
