I don't think you would get information quick enough from a single game even live recording and processing it.
It's not like baseball. 100+ pitches to capture. Fast vs off-speed, bunt, steal. You are basically looking for one signal/combination with one piece of information that tells you exactly what you need to know.
Unless I'm just way off on modern playcalling, football coaches don't have a pass signal, for example. There may be several signals that mean different pass protections that you could group into a passing group. I'm pretty sure this is what Stallions' playsheets do.
And, again, this is something existing scouting software already does. A scout inputs the different variables on any play: GUN FAR | CLOSED | RUN | INSIDE ZONE. Computer spits out "75% of gun far closed formations are runs, 40% being inside zone." All Michigan does is add some signal inputs....computer says LEFT FIST PUNCH OUT = 95% PASS. They probably don't know whether the signal actually means a certain protection or a route concept or what.
