Spencer Brown’s Contract

Spencer Brown is securely locked into a long-term future with the Buffalo Bills, having signed a four-year, $72 million contract extension in 2024 that keeps him with the team through the 2028 season. The deal includes $19.855 million fully guaranteed at signing, providing Brown with significant financial security. The structure of the contract is team-friendly in the early years, with a relatively low cap hit in 2024 that is designed to increase steadily in the later years of the deal.

The contract includes a potential out for the Bills after the 2025 season, though it would come with a substantial dead cap charge of over $22 million, making it more likely that Brown sees out the majority of the deal in Buffalo. This contract is not just a reward for past performance but is structured to compensate Brown handsomely throughout his prime playing years, ensuring a long-term partnership between the player and the franchise.

It’s important to distinguish between cash and cap hit. The cash payout is what Brown actually earns in 2025. The cap hit, which is significantly lower at $8.181 million, is the amount that counts against the Bills’ salary cap. This difference is due to the proration of his option bonus over the remaining years of his contract, a common accounting technique in the NFL to manage cap space.

The major leap came in 2024, the first year of his extension, when he earned $7.88 million. His 2025 salary of nearly $20 million marks another enormous jump. If he fulfills the entire term of his current contract, his career earnings are projected to reach nearly $79 million by the end of the 2028 season.
