Pass. If the receiver is not open, run.
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.
Yes, as long as the quarterback doesn't pass the line of scrimmage. Once past the line of scrimmage, you cannot pass the ball forward
run or jump catch or pass
If he throws the ball and if it gets deflected and goes high in the air he can run up and catch it
whenever he has the ball and is in on offense, but he would probably run if he cant get anyone open to pass to and sees an open gap he can run through to get some yards.
The linemen can only get it on a fumble or a bad pass.
The "pocket" is a horseshoe shaped area formed by offensive linemen that drop back and protect the quarterback during a pass play. In theory, if the quarterback remains within the pocket, he will have sufficient time to find a receiver and throw a pass. If defensive players penetrate the pocket before the pass is thrown, the quarterback is either sacked or forced to run out of the pocket...and then he's on his own.
When the defensive is playing with their safeties deep and have man to man pass coverage, the offensive has a great advantage if they have a quarterback who can run. That's because in the defensive set, no one is covering the quarterback. Well that's fine if the quarterback is not a running one. If he is a runner, then no one is guarding him and he has plenty of room to run for good yardage.
Fake runs are typically called PLAY ACTION. Usually a fake pass is run before a DRAW play with the Running Back or Quarterback then running.
When one or more of the linebackers (and occasionally defensive backs) directly attacks the offensive backfield (where the quarterback and halfback are). The intent of a run blitz is to prevent the offense from effectively running the ball. The run blitz can be countered with a pass, as less defenders are prepared for a pass.
Only if the player was forced out of bounds by a defensive player.
