Adams has been very durable, and hasn't missed a game since 2020, and I think that absence was only due to Covid protocols. So what makes you believe that suddenly we'd end up with $35m on IR?
He has zero guaranteed money in 2025 and no one is giving him a 35M/yr contract. Players get injuries. Players with no guarantees can make sure they are on the roster until salary is guaranteed demand an injury settlement. The Raiders will likely bench him like they did Carr to protect themselves.
