+Let's scrutinize the offensive line and some of the foundation it's based on. Given the policies of the game, there will be five places open to the offensive line. The basic responsibility of the players is to protect the quarterback and backfield. When the play requires running, the offensive line needs to stop the defense and make holes where the runner can go through. The player in the middle of the five positions is the center, who will snap the football to the quarterback. Next to the center, one on each side is where the two guards are positioned. The two spots on the sides of the guards are occupied by the tackles.
+When a pass needs to be caught the wide receivers, split out towards the sidelines, and run down the field looking for the quarterback to throw them the ball. When you watch the players run, the ones with the long, powerful strides are probably the wide receivers.
+The primary duty of a wide receiver is to catch the pass and gain maximum yardage. A wide receiver will also block, when there is a running play. Should another receiver successfully catch a pass, the other wide receiver will immediately try to get into position to provide support with blocking and protection.
+There is always something changing on the field if you know what to look for with American football. College and high school football players must learn how to adapt to changes on the playing field quickly. Playing this game is more about a gut feeling than a preplanned event that requires experience and know-how. Linebackers on the defensive side are the main component of the team used to get to the quarterback. To prevent the offensive team for making a touchdown, the defensive team will often blitz to take down the quarterback. If the defensive line is completely devoted to sacking the quarterback, and they fail, this creates many openings for scoring a touchdown.
+When you decide that you want to play football, be prepared for a physically demanding sport. There are many people who want to be football players, but what sets the really good ones apart from the rest is the desire to improve. Football can be a rewarding sport with the proper positive attitude and dedication to improve oneself.
