Head-up vs. Shaded Technique

Don't know if this is what you are looking for or not, but i've been watching a clinic tape by Dan Brook at Tennessee and here's a couple of things he makes points of emphasis about first step, alignement, etc...

Tennessee plays their d-linemen on one edge of the o-lineman, not head up, so they have their d-linemen put their covered hand on the ground and their covered foot staggered back toe to heel. Their first step is to replace their down hand with their staggered foot, no more no less (need to gain ground to get upfield but don't want to overstride to lose your base). The down hand is the "stab" hand, it does not come back and load/cock to deliver a blow, but gets into the o-lineman's chest/number immediately to keep the olineman from really being able to get his hands on the d-lineman and deliver a blow. The outside hand grabs cloth on the outside of the shoulder pad in the d-lineman's gap of responsibility. According to him, the first step is to get penetration, but by their second step, the d-lineman's needs to know what the o-lineman is trying to do to him (ie base him, reach him, down block, pull, etc).

I would think having the player step with the foot closest to his gap responsibility like CUI suggests above would be the closest to this technique and would help keep the d-lineman from getting mired up in the o-lineman's block...
