Installing the ISO

Coaches, we run our iso in the A gap unless the backer is aligned in the B gap. We Ace Lion the Center and backside guard, we base with the playside guard, and we trey combo with the playside tackle and the tight end. We do it the old fashioned way, but I am always looking to do things a better way. Any advice would be greatly appreciated. Thank you.

Coach Campbell - we got away from the Iso - would like to get back to it. We were seeing a lot or 4-4 with 3's & 7's, so ran more off tackle power along with inside veer. Vs 5-2 teams they would read the double by the center and playside guard and the LB would really fill hard and stuff it at the LOS. Lately we have run it as a lead draw with a slight delay by the TB. We use turn out blocking on the playside when we can. We now see 80% 5-3 and the rest 5-2. What would you suggest vs 5-2's and 5-3's(Tackles in 4i, nose 0, LB's in 60i's and stacked behind the nose, ends are in 9's)

This is how I teach it. It just seemed easier for our kids to learn.

I use the "part the sea" terminology, but I don't call the ISO to a hole. We either ISO right or ISO left. Our blocking rules are, find the uncovered gap and part the sea. Here are two examples....


If you have a 5-3
N- 0
T's- 5
E's-9
Mike-stacked behind N
LB's- Four yards off ball on 4 technique

In an ISO right, the first totally empty gap right is the B gap. So Playside TE and T zone block right and PSG, C, BSG, and BST zone left. Fullback would "iso block" the SLB.



If you have a 6-2
N's-3
T's-5
E's-9
LB's-in A Gap

In an ISO right, the empty gap right would be the A gap. PSG,PST,PSTE would zone right and C,BSG,BS would zone left. Full back would "iso" the SLB.

This gives us the ability to run to the Defense's weakness. If all linemen are stacked, we would run to the first largest empty spot. Against a 3-3 (N=0, T's=4, all LB's stacked behind linemen) we would run this right at the playside guard.

Stacked is the only defense that would be difficult and we would just have to gameplan for that. Usually we try to ISO the Outside LB if the kids get confused.

If you have any questions let me know. I tried to not make it that confusing. It was easy for our kids to learn.
