it is an off tackle play
Zorro mean Z "over" meaning he motions over and "sift" blocks
think of Robert Woods on a wing, he motions from left to right
and blocks the first opposite color shirt he sees while
a fullback lead blocks for the half back to that right side.
The tight end is also on that side----so you have the TE, the FB
and the Z all blocking at the POA, that Z (think robert Woods)
is there to seal the edge upfield (first opposire color) could be
a LBer or maybe a CB
There was one time, while watching the game listing to Peyton and eli
where the Z motion guy forgot to motion, rather, Jimmy G didn't send him
and they still gained yards because the LBer did not follow him and the
Rams thought it was a different play
