I'm watching the game and there is a pivotal moment with 3 minutes left, the opposing punter has been lights out, we've struggled driving down the field the entire game, and clock management has been very poor, I'll boo. It was like a 5 second boo from the stadium. Don't act like it was the entire game or even a significant segment of the game.
And when a good play happens, I'll scream and go crazy.
