we don't run up to the line and snap the ball and just straight forward block. evey run play we have is like this:
a couple shifts. snap the ball on 2 or 3 after the D gets a chance to settle in and make adjustments. after the snap the left tackle drop steps and shoulder turns left to 'wall off' the D-tackle. the left guard slide steps to his gap and pushes the D-lineman. the center chip blocks with the left guard and gets upfield to block the LB. the right guard cutblocks the Nose tackle and creates a hole. the right tackle zone reads the D-end, if the D-end doesn't crash he leaves him and goes to the second level to get the OLB. by this time Lucky has recieved the handoff and has cut between the center and right guard where there appears to be a hole. but wait! while the right tackle didn't misread the D-end, he didn't get to the second level fast enough and the OLB crashes the hole and causes Lucky to break the run a little more to the outside than he wanted. which takes him directly to the waiting D-end who is by now recovering from the misdirection by the Right Tackle. Lucky is unable to break the tackle and is stopped for a 3 yard gain.
if you actually took the time to read this whole thing, then you know how i feel watching the Nebraska running game: lots of movement, some creases, but not quite determined enough, and surely not hitting it fast enough.
i remember being on the practice field when i was 11 years old during the practice week leading up to the 1987 Sugar Bowl vs LSU. Taylor would call the play in the huddle and say "on first sound, first sound!"
the offense would sprint up to the ball, get set and and Taylor would say, "SET!" and the ball was snapped and it was like unleashing a fury. so much forward movement and push, the D simply was not ready for it.
later that nite i asked my dad why they always called it on first sound and he said, "we want to set a pace for the game and show them we mean business. just try to stop it. we don't want them to get settled in. we know what we're running, they know what we're running. A quick count blows them off the ball, straight forward blocking demoralizing the defense."
