'It Smells Like Gunpowder': Vernon Davis Is Offensive Minded

Marines don't use foxholes. Foxholes, as any drill instructor will loudly inform you, are used for hiding from predators. So Marines dig fighting holes.

In the newest Core Of Sports video (sponsored by the U.S. Marine Corps and created by SB Nation Studios), All-Pro 49ers tight end Vernon Davis describes how an offensive mindset is crucial to his performance on the field. Details don't just matter; they're critical.
