Posted under american football blocking rules On By FCY9ZWLtmU

A crackback block is a blocking scheme element where a player split out wide, or in the slot, will motion in toward the formation and deliver a block to the blindside of an edge defender. A crackback block must engage the defender above the waist and, must not be a block in the back.Dec 3, 2015
