ISO Question??

Coach, first, on the Iso, we take maximum splits on the playside (3 feet) to spread the defense. Additionally, v. a 50, we have the PSG false step with his PS foot directly at the ILB. Then, his second step is with his inside foot at a 45 degree angle to double the NG with the Center. Since most 50 teams teach their ILB's to fill immediately when they see a down block, but to check flow when they see a man block, this slows the LB's fill and allows our FB to make contact with him further on the defensive side of the ball. Also, we allow the WG to fold around the double team on the NG to the BSILB, so it is not as important for the PSG to step down immediately in order to combo to the BSILB. We don't do this v. a 4-3 because the C has to snap the ball, and he has a more immediate threat due to the weak side 1 tech, so we don't want to overburden him. He just combos with the WG on the 1 tech to the Will LB.

We have the FB take his first step with the PS foot aiming at the inside hip of the first covered lineman to the PS (v. 4-3, the G; vs 50, the T). We generally want to take it inside of that block if it's a reading defense or if the DT slants out, but this aiming point allows us to adjust to a pinching DT by running the play outside of him.

Once the FB has broken throught the DL level, he is attacking the outside shoulder of the ILB/MLB with his inside shoulder. We use the shoulder block and forarm rip because this play happens so quickly that we want the most aggressive/explosive block we can get from the FB on the ILB/MLB, and punching with the hands has not produced the collision we're looking for. We teach this aiming point for 2 reasons:

(1) if we can get the outside shoulder and force the ILB inside, it allows our TB to cut outside after breaking through the LB level, if needed (if the FS fits into the middle of the formation upon reading Iso), where there is much more running room;

(2) most MLB's/ILB's are taught to attack an Iso'ing FB with their inside shoulder (to keep outside leverage), so the more we attack their outside shoulder, the wider they will attack our FB in order to make contact with their inside shoulder instead, thereby opening the hole up wider to the inside. Upon seeing him widen, rather than filling straight ahead, our FB will then engage the LB's inside shoulder with his outside shoulder driving him outside, and the TB will cut inside the block, then break outside to the backside if the FS fits. Either way, the ILB/MLB is wrong.

To drill this, we just set up game situations with a G, C, G, FB, TB v. 2 DL, 2 LB, FS. We walk through each read first: (1) DT reading or slanting out, (2) DT pinching, (3) ILB filling inside, (4) ILB sliding outside on the fill. Then we go through it half speed, then 100% with the kids knowing what the D will do, and finally we will call the defense and make our offensive people react. Hope this makes sense.
