Lately I have been getting killed on this play. Seem like it develops too slowly. I realize it's supposed to be on "1", with a short motion from the wingback, but it takes forever. In fact the playside DE was in the backfield before the pulling G could even get to him.
First, you have to run the play from "Mini" splits or the timing will be off as well as leakage will occur.
Second, you're running the wrong play. It would work much better versus a "3" tech than a "4".
Try running where they "ain't". Some suggested plays:
"Maxi, 20 Midline Trap"
"Maxi. Left 32 Trap"
"Maxi, right 61 Trap"
"Maxi, right 21 Trap"
And, if you have WB subtract 2 steps from the ball:
"Maxi, Right 41 Trap"
These should all work better than running to "where they are" (a DT and DE side by side.).
