Yes it is a complete pass
Reception or a catch.
The ball is not "out of bounds" unless the ball or the player who possesses it touches the ground in an out of bounds area. So in the case where the ball is in flight over the sideline, and a player who is inbounds catches it and demonstrates control before stepping out, the pass is complete.
For the passer, it's called a completion. For the receiver, it's called a reception.
No, it is considered a completed pass. A receiver may go to the ground to catch the ball, as long as it doesn't hit the ground.
Yes. According to the (new) NFL rules a receiver must maintain possession of the ball all the way to the ground.
Answer Yes.
Yes, the ball is caught incomplete because he was down before he caught it.
it is not a touchdown because the ball never broke the plane.
Any one on the field can catch the ball really. It's primarily the wide receiver or the tight end.
A lateral pass that hits the ground is a fumble, and if the defense recovers, it is a turnover. If the receiver drops the ball after he catches a lateral pass, it is considered an incompletion.
If the receiver gains possession of the ball and then tosses it forward, it's a forward lateral. If he does not gain possession, it's technically just a tipped ball because he never caught it.
Because the ball and the cart are moving at the same forward speed.
