OK I agree with the Kick by the FB from offset. However, to Clarks point about the BSG beating the back, in my mind, I don't see the wrap to LB happening either.
By contrast, I can pull PSG and trap the DL with the BSG. This works better for me at the youth level and gets a Guard out there quicker. Personal experience with pulling has been that the back side puller usually ends up blocking line wash before he gets to the edge anyway.
