Inside Zone or Duo w/Xs and Os

Alright guys... the age old question. Is this inside zone or duo. This shotgun run has all the makings of duo, but it's inside zone. Check out all the reasons why.

I think it is Zone too, but I disagree about the TE. He has C gap and up, he would have been up on the fast flower. The QB has the DE, which the DE would have honored on the pull progression. Then the bend would have been there and that is where the back ended up going.

I think the audio in your video is off or really low.

Wrong. The is Duo. A gap LB is the read.

I think its all Bull. Its def not zone. Based on zone blocking rules its nothing zone about it.
