Cowboys Add Von Miller To NFL's Worst Defense
  • Miller, 37, joins Dallas for his 15th NFL season after nine sacks with Washington in 2025.
  • His 138.5 career sacks lead all active players and tie DeMarcus Ware for ninth all time.
  • Dallas allowed 0.138 expected points per play last season, the worst defensive figure in football.
  • The Cowboys are +2200 to win Super Bowl LXI and +1100 to win the NFC.

DALLAS – The Dallas Cowboys agreed to terms with Von Miller on a one-year contract Sunday, adding the NFL’s active career sack leader to a defense that gave up more expected points per play in 2025 than any other team.

Nine Sacks On 420 Defensive Snaps

The Cowboys announced the agreement Sunday night, hours after Miller posted a photoshopped image of himself in a Cowboys uniform captioned “Hereee Weee Gooo.” He played all 17 games for the Washington Commanders last season but started only three, turning 420 defensive snaps into nine sacks, 26 tackles and six tackles for loss.

That rate matters more than the raw total. A sack every 47 snaps is a real per-play number for a rotational rusher, and nine is Miller’s highest sack total since 2021, when he recorded 9.5 between Denver and the Los Angeles Rams.

The three seasons in between were the worst stretch of his career. He recorded no sacks across 12 games in 2023 while working back from a torn ACL, then six in 13 games in 2024 before Buffalo released him.

His 10.5 playoff sacks also lead all active players. Miller grew up in DeSoto, about a half-hour from the Cowboys’ home stadium.

Expected points per play measures how much each snap moves a team’s expected scoring, so a defense wants the figure as low as it can push it. Dallas’ came in at 0.138 in 2025, the highest in the NFL. Its defensive success rate was 51.1%, also worst in the league, meaning opponents came out ahead in expected points on more than half the snaps they ran.

The pass defense carried nearly all of it. Dallas surrendered 0.240 expected points per dropback, second worst behind only the New York Jets, and 4,521 passing yards, 265.9 per game and the most any team allowed. Opposing quarterbacks averaged 8.1 yards per attempt against them, a rate that moves an offense past the sticks in fewer than two throws.

None of that was an offensive problem. The Cowboys produced 0.100 expected points per play on offense, third best in the league, and 0.180 per dropback. They still finished 7-9-1, fired defensive coordinator Matt Eberflus after a single season and hired Christian Parker, the 34-year-old former Philadelphia Eagles defensive backs coach, to run the unit.

Efficiency splits like these are the backdrop to every season-long Dallas market on the legal sports betting board.

A Rotation Rebuilt Since The Micah Parsons Trade

Miller walks into an edge room Dallas has reassembled piece by piece. The Cowboys sent Parsons to the Green Bay Packers before the 2025 season for two first-round picks and defensive tackle Kenny Clark, then went back to Green Bay in March, trading a 2027 fourth-round pick for Rashan Gary, who is playing on a two-year, $32 million deal.

Gary starts. Second-year rusher Donovan Ezeiruaku and first-round pick Malachi Lawrence are the developmental bet behind him, with Sam Williams, James Houston, Marist Liufau and Tyrus Wheat filling out the group.

Miller’s role is the one he just played in Washington, a situational rusher on passing downs. Parker inherits a room where the snap distribution is genuinely unsettled. Dallas’ season-long prices stay posted through the preseason at legal NFL betting apps and sites.

Dallas Sits Sixth On The NFC Board

The Cowboys are +2200 to win Super Bowl LXI, a price that implies roughly 4.3%. In the conference they are +1100, sixth on a board fronted by the Los Angeles Rams.

TeamOdds to win the NFC
Los Angeles Rams+275
Seattle Seahawks+675
San Francisco 49ers+825
Detroit Lions+900
Philadelphia Eagles+1000
Dallas Cowboys+1100

Whether Dallas’ true chance of reaching the Super Bowl beats what +1100 pays is the whole question. A 37-year-old rotational rusher on a one-year contract is not the kind of addition that repositions a conference.

What Miller gives Parker is a proven third-down option while Ezeiruaku and Lawrence develop, a narrower claim than a futures number would ever register. Dallas carries the same +2200 as the Chicago Bears at legal Super Bowl betting sites.

Dallas opens the regular season at the New York Giants on Sept. 13.
