This is a great video of Ken Hatfield & Fisher DeBerry transforming The Air Force Wishbone Formation into a Flexbone Formation. This added a greater element of the Pass Game to the run oriented pure Wishbone. This is similar to my transition to the Wishbone to the Multi-Bone in the late 1970s and the later to the Triple Gun. These transitions were facilitated by the change in the blocking rules.

Here’s a video on The Air Force Flexbone

I explain the process in my book  Tony DeMeo’s Triple Gun Offense: An Evolution of Option Football, which is available in Paperback at Amazon .
