What Glennon doesn't even mention or didn't notice is the unbalanced line having the 2 guards to the right of center.
It went Mang, Bergeron, Vet, Bleich, Ellis, and Davis so the defense on that side were confused.
They saw a TE but I don't think he's eligible but they don't know that, the motion, fake handoff keeps the first defender on Mang side close to the line, Mang's route keeps the safety away from Gadson.
Brilliant, Brilliant, Brilliant. Unbalanced line, WR in backfield, motion, fake, wide open. Just wow.
