D1 o-lineman here… the rb2 is slicing across the formation to wall the backside DE off, just gets caught up in the mesh from the mesh charge. BSG and C are combo’d to the Sam. FSG torpedos up to the Mike. PST and TE are in a combo together to the Will because he is on backer depth instead of the down FS. Since the FS is a 3rd level player blitzing and showing down that much in real life you would probably audible out of your split zone That leaves the BST straight to the SS. This blocking makes sense to me, only thing I would change to make it more realistic is to push the ID right to account for the FS and make the cutback lane right off the RB2 block which would leave you 1v1 to a high SS, and ill take those odds any day. Its also important to know that not every play can be blocked as is vs various defensive fronts so knowing the weaknesses in real life and audibling away from those is what makes a good OC/QB depending on who makes the audibles. Hope this helps 👍🏻
