So in other words, they cheated.
Not one drop of cheating. If you can figure out what the guy on the field is saying (by voice or hand) then you can use it.
They figured out when his hands signaled he had possession of a hiked football, by overpowering his offensive line and forcing mistakes, they would win the game. Brilliant.
“So in other words, they cheated.”
Not by this...not hardly.
This is a basic part of the game.
