During the 2025 offseason, one of the weakest parts of the Patriots' roster that they needed to address was their pass rush, which Mike Vrabel and Co. addressed almost immediately. Beyond adding Milton Williams, they also brought in linebacker K'Lavon Chaisson, who was coming off a career-best season with the Raiders.
He was given a one-year contract, with most believing it was a prove-it deal that could eventually earn him an extension if he played at a high level, and after seeing how he ended the season against the Dolphins, it would be fair to say he accomplished that and then some.
