It depends on where the quarterback is standing in relation to the receiver. If the pass is forward, it is still a pass even if the receiver is behind the line of scrimmage. If the pass is backwards, it is considered a lateral and therefore a run.
That depends on the angle the ball travelled. If the receiver is behind or exactly to the side of the quarterback and the ball travels at an angle parallel to or away from the line of scrimmage, the throw is considered a lateral and would be a fumble if the receiver did not catch it. If the receiver is in front of the quarterback and the ball travels at an angle towards the line of scrimmage, the throw is considered a forward pass and would be an incomplete pass.
"Legal" receivers are elligable to catch a pass. Players who start a play on the end of the line or in the backfield are elligable. Linemen can't cross the line of scrimmage before a foreward pass crosses the line or they are considered to be downfield illegally unless the pass is caught behind the line of scrimmage.
By definition, a lateral is a pass that is thrown sideways to or behind the passer and is legal anywhere on the field, behind the line of scrimmage or beyond the line of scrimmage.
A sack is when the quarterback is tackled behind the line of scrimmage before he can throw a forward pass/lateral. Tackling the quarterback behind the lime of scrimmage on a running play is not considered a sack.
No! A pass is only legal if it is thrown from behind the line of scrimmage. A pass is illegal if it is thrown from in front of the line of scrimmage.
Yes, as long as he is behind the line of scrimmage when he passes it, it doesn't matter if he has crossed it before. No, once a quaterback crosses the line of scrimmage he is considered a runner and can only pitch the ball backwards
If a quarterback and the entire ball are in front of the line of scrimmage then a forward pass can no longer be thrown but a lateral is still a legal play. However, by the act of crossing the line of scrimmage, the quarterback does not lose the right to throw a forward pass as long as after crossing the line scrimmage, the ball returns behind and is thrown from behind the line scrimmage.
10 yards from the spot of the foul. So if the hold occurred 5 yards behind the line of scrimmage, then the penalty would be a 15 yard penalty from the previous line of scrimmage. The down would be replayed.
Yes.
a sack is when a person tackles the QB behind the line of scrimmage.
When the defense tackles the quarterback behind the line of scrimmage for a loss.
When they are five yards behind the line of scrimmage they call that the SHOTGUN formation.
