Flexbone vs. 4i Odd Front

Here is an example of Georgia Tech running option scheme at a 3-4 odd front structure with DE's in 4i's from Georgia.

Both midline and veer option have challenges against the 4i aligned DE's. That doesn't mean flexbone teams are out of options.

Arc option

Arc option is similar to veer option only the playside OT is arc blocking instead of inside releasing (veer) to the LB. The 4i aligned DE makes the veer release by the OT impossible.
Here GT arcs the OT this makes the 4i DE the Dive key and the OLB (Jack) the pitch key. If the 4i widens with the arc of the OT the QB will give the dive.

The perimeter blocking is a crack arc scheme. The Arc block (OT) is blocking the alley defender. In this case the Safety is coming down. The WR is reading the Corner. If the corner triggers to the alley the WR will crack the safety and allow the Arc (OT) to block the alley player. Since the Corner stays wide the WR blocks the Corner.

Good play design from Paul Johnson and good execution from the Yellowjackets. This is a play to prepare for if you run 4i DE in the odd front and expect to see a flexbone option offense this season.


  1. You can't stop everything. Take away their core plays and make them do something different.

    1. It's true there is no perfect defense. Flexbone coaches are great at if/then game planning. If you present any look then they have something they feel attacks that look. This article is about one of those then concepts flexbone teams have for odd front defenses using a 4i. The article is about 2nd plan for defense. Deny what a flexbone team does best with your 1st plan. When they make in game adjustments do you have a well developed 2nd and 3rd plan? The goal is be ready to stop the "something different" you forced them into doing.
