Inside Zone vs. Stack 4/4.. Coach Campbell and others !!

Starting from the backside, if you are in the "I," this will be a split-flow play, with the fullback responsible for the backside 5-tech. The backside OT and OG are responsible for the 2i/1 and the stacked LB . The center and the playside OG should have an ACE combo on the 3-tech to the stacked LB. We have found that on our inside zone runs we have to stress to our OL that we are going to stay on the 1st level defender until move him into the 2nd level defender.
Now, if this is a true 4-4 stack, then I would assume that the tackles are in 2-techniques with the LB's stacked. If the tackle is in a 3-tech then it is pretty safe to assume that there is an A-gap LB, making an ACE combo a little easier. On the backside, if the tackle is in that 2i/1 then the DEUCE combo is a little easier also, with a B-gap LB.
As for expecting an automatic cut-back, I would tend to stay away from telling a runningback to automatically cut-back. Obviously, we want to give our backs an advantage by teaching them what is most likeley to happen, but you never know what is going to take place.

Sounds great.

You could use that to help set up the "BOUNCE" play that Coach Campbell talks about. Instead of the TREY-OUT combo, TE/OT combo to ILB, and FB bounces out to OLB.

We "zoned" our Wham/Iso play (like you describe) the last two years with great success.

My thinking with this type of front is that by sending the fullback on the LB you have a frontside and backside option, at times it is very difficult to get that Ace combo by the playside guard and center. The center really has to stretch and get there. It limits you on the frontside a bit, but the cutback should be there.

ayeziggyzoomba,

How would you block the inside zone against an underfront? (shade,5 ,9 playside) 3 and 5 backside?
