Stefon Diggs is signing with the Washington Commanders, a big addition at wide receiver to give quarterback Jayden Daniels and the offense a proven commodity who showed last season he can still be productive more than a decade into his NFL career. The Commanders agreed with Diggs on a contract for this season, according to multiple reports. Diggs, a native of nearby Gaithersburg, Md., joins Washington for a 12th year in the league and reportedly can make up to $12 million. The Commanders had a hole at the position, and they are banking on Diggs filling it. Signing Diggs could rule out going after Brandon Aiyuk, a friend of Daniels’ who is still under contract with San Francisco.
