1. Agree with the presnap motion, though I will say that I generally only find that to be effective with teams who have outstanding speed that needs to be covered. Brown forces that action, and Duvernay to an extent, but like motioning somebody like Boykin or Snead isn't really going to force much manipulation on defense.
2. I'm generally not a fan of moving the pocket that often. For starter, I don't think it benefits Lamar's skill sets in particular, and by definition, it cuts the field at least in half, if not more so. Lamar is at his best when he's attacking the middle of the field, with multiple options, and from the pocket (in my eyes). One of my critiques of him this year, at least in my eyes, is he's fleeing the pocket too quickly, scrambling after merely a second or two, and not always allowing the play to develop.
I do like RavensMania ideas with RB screens. We do so little of that its comical.
