Amen. It doesn't have to be a long TD to help set up other plays later. Too often the formations and play calling we ran made us predictable and allowed teams to hug the LOS with their safeties. Running plays like that can get the D flowing the wrong way for even one step or two is all it'd take...<<For crying out loud once a game wouldn't even be too much for plays like that>>
And the other thing is, the play doesn't always have to be "successful" for it to have an effect. Just the knowledge that we will use it can be enough to take that 8th or 9th man out of the box.
