• The San Francisco 49ers have had a lot of success over the last few years, and much of the credit should be going to the defensive unit.
  • That unit is led by middle linebacker Fred Warner, who serves as both the play-caller and the beating heart in the middle of the defense.
  • According to former teammate and All-Pro Joe Staley, it's Warner's incredible dedication to improving himself and his game that has allowed him to become one of, if not the best middle linebacker in football.
