As noted following the scrimmage on Saturday, Virginia Tech is putting in a new pistol formation offense this spring. With the amount they worked on the pistol formation during the scrimmage, I don’t think it's unfair to say that the staff is considering basing their entire offense around the pistol this year. When the spring is over, they'll reflect on their personnel and how they performed, and then make the final decision before practice begins in August.
I'm not the best X's and O's guy in the world, but I'll do my best to describe the pistol offense, why it was created, and why Virginia Tech is considering moving in that direction.
