THE PRIMARY GOAL of the read-option is to give RG3 enough time and space to ride the RB into the mesh point, where he can either hand off or keep based on how the edge defender reacts. Here, the O-line blocks opposite, disguising this as an off-tackle run. But RG3 and RB Alfred Morris follow the pulling tight end/H-back to the back side; the D is forced to play contain, not allowing RG3 the edge. That opens an inside hole for Morris, who had 324 yards on option runs last season, third most in the NFL.
