After three mostly productive seasons in Washington, Brian Robinson isn't quite sure why things didn't work out with the Commanders.

New San Francisco 49ers running back Brian Robinson Jr. is excited to form a backfield duo with Christian McCaffrey.

The 26-year-old was traded from the Washington Commanders to San Francisco on Friday, with the deal being made official on Monday, and after his first practice with his new team, spoke to reporters about his hectic weekend uprooting from the organization where he spent the previous three seasons.
