Christian McCaffrey’s imposing reaction to 49ers rookie tailback will rile up fans

Christian McCaffrey praised rookie tailback Kaelon Black during training camp, describing him as stacked and noting his high level of football experience. While Black makes a strong impression on veterans, the San Francisco 49ers are currently addressing depth issues in their backfield. Following a rib injury to Jordan James, the team worked out three different running backs this week to determine the best options to serve as backups for McCaffrey throughout the season.
