To those of you who believe "too bad....get better", it is obvious that your team is usually on the winning side. To the ones that believe that any coach can make a football team, there is this little thing called TALENT that is needed. Many schools have to dress everyone that comes out for the team, while others have the luxury of picking through alot of talented players. There are alot of factors that lead to a blowout. But that is not the topic, running up the score is.
To leave your starters in the game when the win is secure is inviting the other team, the ones getting embarrassed, to take a cheap shot at your starters, and injurying them. You say, "That is not very sportsman like," they feel the same way about you running up the score. I am not saying that any coach would tell their players to do that, but these players are just kids in a uniform and they make alot of their own decisions when on the field. I know I did.
When up by 4 touchdowns in the second half, it is more beneficial to get some playing time for your younger players. If the other team can not stop them either, there is nothing left for you to do.
Those of you who think the score should be ran up, wait until you have kids on the sidlines and in the game.
