A-11 Football is an offensive system used in some levels American football in which a team's offensive players are deemed eligible to catch a forward pass - as determined by the formation they're aligned in, and not according to their jersey number and formation - as is the case in basic American football. A-11 Football allows all of the team's offensive players to be interchangeable in their sets because they are not restricted by jersey numbers, like they are in basic football. A-11 Football allows for 16,632 possible post-snap scenarios of which player can receive the snap and advance with the football because any player can align in any spot within any formation - thereby making A-11 players interchangeable. In basic American football using a five fixed offensive linemen set, there are only 36 possibilities of which player can receive the snap and advance with the ball because the offensive linemen are not interchangeable within the formation with other offensive players - the jersey-numbering requirement does not allow it.
Yes. Encroachment is when a defensive player makes contact with an offensive player before the snap of the ball.
If an offensive lineman moves, a false start penalty will be called. It is not fair to the defense if the lineman moves before the snap because it would give the offense a huge advantage.
Sure what team?=============On the offensive team, there are linemen and backs. The interior linemen are the centre, two guards, and two tackles. The interior linemen are not eligible pass receivers.The center snaps the ball, and on either side of the center is a guard. The tackles line up outside of the guards.There are also two ends, who are linemen and eligible pass receivers. They line up outside of the tackles, and often far outside of the tackles.All seven linemen must be on the line of scrimmage when the ball is snapped.In the backfield, there is usually a quarterback and at least one running back. Sometimes there is a second running back or a blocking back. There is usually a backfielder who lines up far outside the rest of the players, and often two of them, usually referred to as wide receivers. Backfielders must be at least one yard behind the line of scrimmage at the snap of the ball. Only one backfielder can be moving before the snap, and he can not be moving forward. All backs are eligible pass receivers.The defense has much more freedom in positioning and is allowed unlimited movement prior to the snap, provided that they are not offside. Usually there are two defensive tackles and two defensive ends on the line. Behind them are usually three or four linebackers, and behind the linebackers are the defensive backs.There are usually two outside linebackers and one or two inside linebackers. One of the defensive backs is usually called the safety. There is sometimes a strong-side safety and a weak-side safety.These are general terms. The actual positions and names can vary from team to team, and also, depending on the circumstances, within a game.

When the referee places the ball on the ground, no player on either team (except the center on offense) may may line up with any part of their body inside the neutral zone.

Strength, the center must be able to neutralize defensive linemen that are as strong if not stronger than they are.

Intelligence, the center will usually call offensive line assignments at the line of scrimmage and must be aware of the defensive setup. Discipline, the center must always snap the ball on the count called by the quarterback.
