Allen is due $17 million in cash for the 2025 season as part of the last year of his player contract.
Allen requesting a trade would logically mean that Washington is not willing to extend his current contract or that the two sides cannot agree on the numbers for an extension. Any team that trades for Allen should be prepared to complete a contract extension immediately after the trade is completed.
Most teams will likely wait for Washington to release Allen, and then attempt to sign him to a favorable contract as a street free agent. This path will lead to a lower-value contract.
