Also, just from the aspect of a former lineman who ran a ZBS in HS, i was told that if its a run to the right, your man is the man head up on you to "inside eye" (shaded inside) of the next OL over. The idea is basically all the linemen go one way, and try to hook their man back away from the playside, if their not able to get out there, keep pushing him TOWARDS the playside, so eventually down the line, one man will hook block, or everyone will be pushed down to create a lane. If you block it right, in theory its unstoppable, but with big NT's and fast filling linebackers, it makes it a lot harder.
If I ever meet someone who believes anything creates guaranteed success, I'll mention you advised them to avoid getting involved in sports conversations.
