Darn wish I saw this earlier. As someone who played in college I like having the full picture. Now that I have a projector at home would have loved to go over it. The big missing piece you dont have is the playbook and what was expected on the play from all parties.
That is the missing piece as far as grading/analyzing the play and the player. For the most part you can deduce it but its alot easier/faster if you have the knowledge upfront. Also much of the NE passing game is sight/route adjustments based on how the defense lines up. That would also be tricky to figure out if someone saw the option route as a stop vs an out etc. Not sure why its such a closely gaurded piece of film.
