line of scrimmage
yes they do
15 yards; can be from end of the play or the original line of scrimmage.
Dropkicks can only be attempted on a play from scrimmage, not on a kicking play that restarts the game.
The offense is allowed up to ten players on the line of scrimmage, need one to receive the ball from the center. But the offensive is required to have a minimum of seven players on the line of scrimmage. Defensively all eleven can play on the line of scrimmage.
Seven on offense. No requirements for the defense
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.
I've never heard that term, but I would assume it means a touchdown scored from a play that originated at the line of scrimmage, as opposed to a touchdown scored on a kickoff return.
