One very simple scheme I used when i ran NE was Iform tight.I switched books and I miss this the most.
run-power O.I would motion the WR till he got behind the RT,RG or as close to the QB as possible.It just depends on how the D is trying to stop the run.I think what helped me on this one is I would read the blocks and take the first hole.Most of the time it was between the RG and RT with my WR leading the way.I broke off good chunks off yards and quite a few big plays against good players not bums.
Pass-z spot. From the motion in the run play and auto motion in this play its pretty easy to tell if their run d is man or zone.The flat route is going to beat man up pretty good and the spot can beat man and zone.The TE on the post and corner are good looks but against a blitz its tuff to get off.
You want them to think your running to open up z spot.I know this not in the gun but this was my bread n butter mini pound game for about 1 1/2 months.
