Option, as in Georgia Tech's offense. This can only be done in the Steelers playbook tho.
Pick
any of the plays out of wildcat(Jet Sweep is the best), and wait for
the playclock to get to 3 seconds. Hike the ball, and the A-M WR should
start running towards Willie Parker, but he won't make it all the way
leaving him a few feet being Parker, allowing you to pitch the ball
back if needed on a heavy blitz.

You can also use the power play to do this since the WR will keep running behind the HB instead of going to block.
Also,
by waiting until the playclock is low and not letting the WR get to the
HB in time, it seems like it gets you better runs. I've taken a few
with Willie to the house and one with Santonio
Good luck!
