@vaporeon_ yeah but does c++ have the following definition of "player possession"?

"A player is in possession when he is inbounds and has control of the ball with his hands or arms.

To gain possession of a loose ball that has been caught, intercepted, or recovered, a player (a) must have complete control of the ball with his hands or arms and (b) have both feet or any other part of his body, other than his hands, completely on the ground inbounds, and, after (a) and (b) have been fulfilled, clearly perform any act common to the game (e.g., extend the ball forward, take an additional step, tuck the ball away and turn upfield, or avoid or ward off an opponent). It is not necessary that he commit such an act, provided that he maintains control of the ball long enough to do so. This rule applies in the field of play, at the sideline, and in the end zone.

Notes:

• Movement of the ball does not automatically result in loss of control.
• If a player who has completed the first two, but not the third requirement for possession, contacts the ground and loses control of the ball, there is no possession if the ball hits the ground before he regains control, or if he regains control out of bounds.
  • If a player would have caught, intercepted, or recovered a ball inbounds, but is carried out of bounds, player possession will be granted (8-1-3-Note 5).
• If any part of the foot hits out of bounds during the normal continuous motion of taking a step (heel-toe or toe-heel), then the foot is out of bounds. A player is inbounds if he drags his foot, or if there is a delay between the heel-toe or toe-heel touching the ground.
• The terms catch, intercept, recover, advance, and fumble denote player possession (as distinguished from touching or muffing).

A catch is made when a player inbounds secures possession of a pass, kick, or fumble that is in flight. An interception is made when an opponent who is inbounds catches a forward or backward pass or a fumble that has not touched the ground.

Notes:

• It is a catch, or an interception, if, in the process of attempting to possess the ball, a player secures control of the ball prior to it touching the ground, and that control is maintained during and after the ball has touched the ground.
• In the field of play, if a catch or interception has been completed, and the ball comes loose before the player is down by contact, it is a fumble, and the ball remains alive. It is also a fumble if the action occurs in the end zone of the player who caught the loose ball. If the action occurs in the opponent’s end zone, it is a touchdown or a touchback.
• A recovery is made when a player inbounds secures possession of a loose ball after it has touched the ground.

If a loose ball is controlled simultaneously by two opponents, and both players retain it, it is simultaneous possession, and the ball belongs to the team last in possession, or to the receiving team when there has been a free kick, scrimmage kick, or fair catch kick. It is not simultaneous possession if a player gains control first and an opponent subsequently gains joint control."
