re: What is the best way to counter if our OL struggles?

12 personnel/Pistol/H deep set inside shoulder TE

Crash block toward TE / Pull TE side guard / HB follow guard / Rb counter toward TE then cut back to follow HB.

Those teams that slant the D toward the TE have caused issues. This get the flow toward the TE then 34/8 cutback against that flow and read the hole at back side tackle. Guard kick out and HB lead like from an old I-set.

I would at least try it a couple of times to kill their desire to slant the D-line also keeps LB eyes in the backfield and away from the Slot slant/wheel passing.
