When the play starts run to the defensive backs inside shoulder about ten yards deep, then do a loop-d-loop (do a 360 degree turn clockwise, you should end up back on his inside shoulder but a step ahead of him) and sprint to the endzone.
But, make sure to stay very straight once you are heading to the endzone or the pass may be inaccurate.
If done correctly you will get several touchdowns and the d-back will give you a very large cushion. When this happens just run a curl or crossing pattern.
