I think that almost every coach at every level "scripts" at least the 1st series or two. Designed to attack possible weakness from film, but more importantly, to see how the D will line up vs different formations, allowing offense to calculate how to attack. I think you HAVE to script a few just for this reason only. You can't fly by the seat of your pants, and just "hope" the D lines up how you want it (unless you are Mike Leach).
I really hate to go into play calling, because it is all relative to the outcome of the play......if one works, it is great, if not, we should have called something different....and, the coaches are where they are for a reason, and we are where we are for a reason.
Now, with that said, I am a play action and bootleg coach. It is one of my staples, especially in red-zone. I would love to see a little more naked boots with QB inside 5, .....the way the D was pursuing and if you fake to Castille behind Suh, Ganz would have walked to end zone a couple of times. Finally, on third down inside the 5, a drop-back pass is extremely difficult. We did this a lot. When the D can drop 7 at the read of the snap, into a short coverage area...this is not an easy d to pass against.....from inside the 5, the run is still a possibility, so the D would have to respect the run/ball fake a little, causing the LB to freeze, allowing more space to work with.
I think Watson and Co. will adapt to the talent they have and nothing I could suggest/want would really matter. Go Big Red.
