Icing Kickers

An unethical part of football would be when opposing teams "ice a kicker." Icing a kicker is when opposing team's head coaches call a timeout right before the ball is hiked. Opposing teams usually do this for potential game winning field goal attempts in order to try and psych out the kicker and make him think more about the kick. In some instances, the opposing team calls a timeout, but the kicker still kicks the field goals and makes it. But then on the real kick on the next play, he ends up missing the field goal and losing the game for his team. There has been a good amount of discussion about whether this is unfair, or just part of the game. I believe icing the kicker is unethical because teams know what they are doing by getting in the head of the opposing kicker and possibly causing him to mess up and lose the game.
