Nice to see all the usual suspects that have no clue how to read a rule, know what a case book is and how it is used, or what is clearly a change in the rules is.
Here is the Rule as it was written in 2012, 2013, and 2014:
ARTICLE 3 - COMPLETED OR INTERCEPTED PASS.
A player who makes a catch may advance the ball. A forward pass is complete (by the offense) or intercepted (by the defense) if a player, who is inbounds:
- secures control of the ball in his hands or arms prior to the ball touching the ground; and
- touches the ground inbounds with both feet or with any part of his body other than his hands; and
- maintains control of the ball long enough, after (a) and (b) have been fulfilled, to enable him to perform any act common to the game (i.e., maintaining control long enough to pitch it, pass it, advance with it, or avoid or ward off an opponent, etc.).
Note 1: It is not necessary that he commit such an act, provided that he maintains control of the ball long enough to do so.
Note 2: If a player has control of the ball, a slight movement of the ball will not be considered a loss of possession. He must lose control of the ball in order to rule that there has been a loss of possession.
If the player loses the ball while simultaneously touching both feet or any part of his body to the ground, it is not a catch.
Item 1: Player Going to the Ground. If a player goes to the ground in the act of catching a pass (with or without contact by an opponent), he must maintain control of the ball throughout the process of contacting the ground, whether in the field of play or the end zone. If he loses control of the ball, and the ball touches the ground before he regains control, the pass is incomplete. If he regains control prior to the ball touching the ground, the pass is complete.
Item 2: Sideline Catches. If a player goes to the ground out-of-bounds (with or without contact by an opponent) in the process of making a catch at the sideline, he must maintain complete and continuous control of the ball throughout the process of contacting the ground, or the pass is incomplete.
Item 3: End Zone Catches. The requirements for a catch in the end zone are the same as the requirements for a catch in the field of play.
Note: In the field of play, if a catch of a forward pass has been completed, after which contact by a defender causes the ball to become loose before the runner is down by contact, it is a fumble, and the ball remains alive. In the end zone, the same action is a touchdown, since the receiver completed the catch beyond the goal line prior to the loss of possession, and the ball is dead when the catch is completed.
Here is 2015:
ARTICLE 3. COMPLETED OR INTERCEPTED PASS
A player who makes a catch may advance the ball. A forward pass is complete (by the offense) or intercepted (by the defense) if a player, who is inbounds:
- secures control of the ball in his hands or arms prior to the ball touching the ground; and
- touches the ground inbounds with both feet or with any part of his body other than his hands; and
- maintains control of the ball after (a) and (b) have been fulfilled, until he has clearly become a runner (see 3-2-7 Item 2).
Note:
If a player has control of the ball, a slight movement of the ball will not be considered a loss of possession. He must lose control of the ball in order to rule that there has been a loss of possession.
If the player loses the ball while simultaneously touching both feet or any part of his body to the ground, it is not a catch.
Item 1. Player Going to the Ground. A player is considered to be going to the ground if he does not remain upright long enough to demonstrate that he is clearly a runner. If a player goes to the ground in the act of catching a pass (with or without contact by an opponent), he must maintain control of the ball until after his initial contact with the ground, whether in the field of play or the end zone. If he loses control of the ball, and the ball touches the ground before he regains control, the pass is incomplete. If he regains control prior to the ball touching the ground, the pass is complete.
Item 2. Sideline Catches. If a player goes to the ground out-of-bounds (with or without contact by an opponent) in the process of making a catch at the sideline, he must maintain complete and continuous control of the ball until after his initial contact with the ground, or the pass is incomplete.
Item 3. End Zone Catches. The requirements for a catch in the end zone are the same as the requirements for a catch in the field of play.
Note: In the field of play, if a catch of a forward pass has been completed, after which contact by a defender causes the ball to become loose before the runner is down by contact, it is a fumble, and the ball remains alive. In the end zone, the same action is a touchdown, since the receiver completed the catch beyond the goal line prior to the loss of possession, and the ball is dead when the catch is completed.complete the process.
Here is the Definition of a runner as cited in the rule
CHANGE:
Item 2. Possession of Loose Ball. To gain possession of a loose ball that has been caught, intercepted, or recovered, a player must have complete control of the ball and have both feet or any other part of his body, other than his hands, completely on the ground inbounds, and then maintain control of the ball until he has clearly become a runner. A player becomes a runner when he is capable of avoiding or warding off impending contact of an opponent. If the player loses the ball while simultaneously touching both feet or any other part of his body to the ground, there is no possession. This rule applies in the field of play and in the end zone.
Note that there is nothing in the rule or case plays from 2012-2014 that in any way suggests that the player needs to complete the process before he begins going to the ground. In fact as has been shown the exact opposite was true.
Here it is from 2012-2014:
Item 2: Possession of Loose Ball. To gain possession of a loose ball that has been caught, intercepted, or recovered, a player must have complete control of the ball and have both feet or any other part of his body, other than his hands, completely on the ground inbounds, and maintain control of the ball long enough to perform any act common to the game. If the player loses the ball while simultaneously touching both feet or any other part of his body to the ground, there is no possession. This rule applies in the field of play and in the end zone.
As with the catch rule, the change was made just to remove part C of the old rule, the part Dez did when he turned, took a 3rd step, switched the ball to his left hand, braced, and extended the ball.
Now the fact that the rule never changed and there was never a point of emphasis from 2012-2014 means that the case book in 2012 was still how the play was intended to be called. The change in 2015 was to make the overturn justified, it had no basis in rule from 2012-2014.
