That's true on all plays.
One guy messes up, that's all it takes.
One lineman doesn't block his guy, the play blows up.
Open guy drops a pass, RB hits the wrong hole, same thing.
Blocked FG or punt, and it can kill you....as we saw last game.
Coach tries to over think, or calls the wrong play or defensive call, you lose.
Pretty simple to see. But for the Packers, not easy to fix. But it SHOULD be. Unless the talent isn't there, or the coach isn't smart enough to put the players into the spots where they belong and can use their talents.
