Football is the most popular sport in America, for sure. However, it is not as popular in many other places of the world. For lots of proper who just started watching football, it looks like a bunch of big guys trying to tackle each other, especially the guy who is holding that ball. The game seems quite violent and dangers because there is so much physical impact in the game. But actually all the players are very well trained and protected by theor equipment and experience. And when you really understand the rules of footbal, you will see it is such a fun sport.
There are 53 active rosters on each team, 11 of them play on the field each time. Let us talk about the positions on offense first.
Quarterback: as I know, he is the “core” of a team. He catches the ball from the center when the offense starts, and decide wether to pass the ball to a wide receiver or a running back, or just take care of the play by himself.
Center: this guy is the one in the middle of the offense line. He passes the ball to the quarterback at the beginning of an offence.
Wide receive: they are always on the wide side of the offence line and ready to catch the ball passed by the quarterback.
Running back: they are the ones behind the quarter when offence starts. They get the ball from the quarterback and try to find a “hole” of the defense line to run through. Then they run as fast as they can to get a touchdown. And yes, they might be the fastest guys in the team.
Offence guard: the 2 guards are placed on eather side of the center, they protect the quarter back and the running back.
Offence tackle: the 2 offence tackles are lined up outside of each guard. They are protectors as well.
The duty of each position might vary depends on the play.
