The San Francisco 49ers sent a message to the rest of the NFL when they were able to acquire one of the most dangerous offensive weapons in the league last season.
With the Niners chasing a Super Bowl they were able to pull off a trade to bring in superstar running back Christian McCaffery from the Carolina Panthers.
McCaffery had spent five-and-a-half years with the Panthers, being a fan favourite with the franchise although through a difficult period in the team's cycle - making the playoffs just once in that time.
