The actual playbook in its entirety is pretty interesting. Coach Bryant's influence on the game is still strong.

Bill Belichick’s father Steve Belichick is credited with being the first modern football “scout” and for creating and defining terminology that is still used to evaluate individual talent today.Bryant created terms and terminology to define techniques for entire schemes that are used at every level of football today.
A good example is the “gap” system. The system used to number/letter the gaps between lineman and define techniques/alignments.
When you hear an announcer say a lineman “plugged the A-gap” or that he’s lined up as a “three-technique” those are terms Bryant invented.
