Kalen DeBoer is entering his first season leading the Alabama Crimson Tide. As a head coach, this is his fourth stop. His overall record: 104-12. That includes three national championships at his alma mater, the University of Sioux Falls, an NAIA school in South Dakota. DeBoer has been a winner everywhere he's been not only as a head coach but as a coordinator. But his biggest challenge awaits him: Replacing the legendary Nick Saban.
