From the old English sport of Rugby, in time, came American football, an unquestionably thrilling game to watch. The game is very complex, with multiple specialized positions and in-depth strategies involving them. No matter whether one is watching a game from aluminum bleachers or a big stadium’s chairs, this complexity assures that that fan will be gripped.
Different on-field units are utilized by each squad during the game. The goal of the offense is to either register a touchdown or get the team close enough to the opposing team's end zone for a field goal. To begin a play, the quarterback, who is in essence the boss of the offense, gets the snap from the center, or head offensive lineman. He will either hand the ball off to the running back or throw it downfield to a qualified receiver. The quarterback is also in charge of relaying the pre-snap schemes the head coach creates to the rest of the players on the unit. On certain plays, the running back endeavors to bring the ball downfield making use of gaps in the defense. On passing plays, wide receivers go along different routes down the field and try to get open to more effortlessly haul in a pass from the quarterback. Offensive linemen block defensive players as much as possible so that they cannot disturb the quarterback while he tosses or the running back in the midst of his run. On numerous plays, the tight end acts as an extra offensive lineman, and on several others, will be an additional pass catcher. The running back is further protected on run plays by the fullback, who is a more motile bodyguard than the linemen. Dependent upon the scenario, the fullback can be swapped out for another tight end, and any man on the offensive unit can assist in blocking.
The defense has three different main position sets: the defensive line, the linebacking corps, and the defensive backfield. Quite a few teams employ four linemen and three linebackers, and some use the reverse configuration, based on the defensive assistant coach's philosophy. All defenders are charged with bottling up the run on running plays. On pass plays, the linemen and linebackers more often try to keep the opposing quarterback from firing by sacking him, and the defensive backs generally try to stop receivers from making catches. Amounts of defenders of each type can also fluctuate from play to play as appropriate.
The special teams collectives that are involved in kickoff, punt, and field goal plays comprise the third “phase” of the game. The true specialists on these types of teams are the kicker and punter, with most other players on the team wanting for their skills. Punt and kickoff return groups use a speedy player referred to as a return man to run the ball back as far as possible and negate some punt or kick yardage. Other than these, special teams utilize players who can either block, tackle, or halt ball movement depending upon the specific team on the field and the ball's current position.
All the various positions of the game and their interplay on the field make football an utter joy to watch, no matter if one is in high school stadium bleachers, pro stadium seating, or anywhere else.
