Former 49ers quarterback Sam Darnold believes Christian McCaffrey’s internal motivation is crucial for his bounce-back season, emphasizing that McCaffrey is driven by a desire to prove himself rather than external factors. Darnold, who played with McCaffrey at the Panthers and again with the 49ers, noted that McCaffrey’s determination is unmatched, though head coach Kyle Shanahan acknowledged the need to manage McCaffrey’s training to prevent injury. McCaffrey has shown strong performance in recent practices, indicating he is ready for the upcoming season.
