The true way to stop zone read:

I'm a HS head coach who runs the zone offense. Gap exchange is the key to stopping it. Focus on the back side.

A) Have the 5-tech stay in the C, have the will take read steps into the B
B) Have the 5 crash the B (squeeze) and the will read the C.

This will change who the Q sees as "EMOL" but post snap.
