Yes you can throw as many passes as you want as long as you or the ball has not crossed the line of scrimmage, but once you or the ball has crossed that line, you may not forward lateral the ball to another player, the pass must be a backward lateral.
incomplete pass
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.
Up until just recently, it was judged as where the ball is. Now, if any part of the person throwing the ball, even just a foot, is behind the line of scrimmage, that is a legal pass.
Typically it's 7 yards. So if the line of scrimmage is on the 35 yard line then you add 7 yards for the kickers depth behind the line and then 10 yards for the depth of the endzone totaling in a 52 yard field goal.
In the NFL, there is no such thing as pass interference (PI) on forward passes that do not go past the line scrimmage but I recently watched a college football game in which a PI was called on a forward that never reached the line of scrimmage even though I always believed that there is no such thing as PI if such pass was in the backfield (behind the line of scrimmage). So I am not clear on the rule concerning passes that do not cross the line of scrimmage, in college football.
yes
An illegal forward pass happens when the QB crosses the line of scrimmage and then passes the ball forward or when a forward pass has been thrown and the player holding the ball passes forward
The offense must have 7 players on the line of scrimmage.
