Tua time!
To my knowledge teams generally run 15-20 game plays during the walk through.
If the QB calls out adjustments you now have tape of his hand signals and see what the O-line, RB's, WR's do after the handsignals and transfer that to game day.
If a team knew every time Peyton yelled 52-Switch and tapped the side of his helmet ment the O-line shifts to the right, WR corner route....yeah huge.
So now you know 52-switch means O-line shift, multiply that by another 15-20 plays etc...
dont tell me they also got audio of all the checks and line calls???
