In this post, we're going to look at A-Gap Power. A-Gap Power itself is not new. As I detailed in "History and Evolution: Power O" , what we know today as standard power was really the B/C gap constraint to the more traditionally Power Sweep. But by the late 70s and early 80s, you started to see variants of A-Gap Power schemes appear as teams wanted to protect their off tackle runs by showing a puller, but hitting inside. Teams like NDSU and Wyoming made a lot of hay off a specific type of A-gap Power, and as they've had success and their former coaches and disciples and knowledge have branched out all across football, you see this specific type of A-Gap Power arise elsewhere. This post is going to go over a few of the basics of A-Gap Power.
