The San Francisco 49ers are still facing uncertainty with Christian McCaffrey, so one former All-Pro thinks the team needs a trade.

San Francisco still doesn’t have a clear timeline for McCaffrey’s return, which is why two-time All-Pro RB and current NFL Network analyst is urging the team to reunite with Miami Dolphins RB Raheem Mostert.

“However, with no guarantee that the reigning Offensive Player of the Year takes a snap this season and Mason’s recent scare, Shanahan could look to replenish his backfield,” MJD wrote on October 16. “Mostert and Wilson are solid veteran options who would add some quality depth to this 49ers attack. Plus, the Dolphins have a pair of young running backs in tow: second-year stud De’Von Achane and budding rookie Jaylen Wright.”

Jones-Drew makes a good case for why a reunion would work as well as why Miami might deal Mostert. The 49ers can reinforce their backfield with a player who knows Kyle Shanahan well, while getting him for a cheap price.

At the end of the day, it’s just a suggestion but there are multiple signs that point toward this being a legitimate possibility.
