variation on speed option

The easy answer would be to simply check the play to the trips side. Your inside receiver would crack on the first LB inside and the 2 outside receivers would stalk. It may end up being a QB keeper with everyone getting blocked and the FS becomes the force defender. Another way would be to run doubles. Now you can crack the inside LB to both sides, stalk block the corner with your WR, and pitch off of the invert. You can accomplish the same thing from trips with motion, but you will give them a motion tendancy.

My more thorough response would be this: If you have a trips open formation, I expect the defense to put 3 perimeter defenders out with the free safety either in the middle or cheated to the 3 receiver side. With the corner covering the backside receiver, the defense can only put 6 in the box. If they want an invert on the weakside, they have to play with five in the box, against which our first choice would be to run inside. The only way the defense can play with an invert and put six in the box is to not cover one of the trips receivers. Sometimes defenses try to cheat and put only two defenders out and cheat the free safety over to the trips side. If they do, we will run bubble screens or sprint out and flood the trips side until they remover an interior defender with our third receiver. When given the choice between taking a box defender out or playing without a free safety in the middle of the field, most coaches will bump a LB out.

I guess what I'm saying is this. If the defense is going to strengthen their weakside perimeter defense, it is going to be at the expense of some other part of their defense. Find out where and take advantage of it.
