What happened: The deal averages $35.3 million annually and includes $63.35 million fully guaranteed. Nicole Lynn of Klutch Sports negotiated the agreement.
Why it matters: Dallas acquired Quinnen Williams at the 2025 trade deadline and has now secured its defensive centerpiece beyond the upcoming season. The extension is the largest third contract for a defensive lineman.
By the numbers: The $101 million guarantee equals 95.4% of the $105.9 million in new money. The $63.35 million fully guaranteed portion represents 62.7% of the total guarantee.
What to watch: The final contract structure will determine how Dallas spreads the cap charges across the added years.
