For anyone out there who is confused by this trolls misuse of the rule book:
Case plays are intended to illustrate the rule. The reason there are multiple case plays is because there are multiple ways that the rule might have to be applied.
The rule book says a player must A) control the ball B) get 2 feet in bounds C) have time to or make a move common to the game in order for it to be a catch and a receiver becomes a runner. Simple enough, but then it adds notes.
Item 1: A player going to the ground must maintain control of the ball through contact with the ground.
What does this mean? Well, trolls will tell you it is the end all of all rules, but it isn't. Items are exceptions for when the actual rule above is not or will not be met.
For example:
The sideline: A player must have control and 2 feet in. So you will have a case play where a foot lands on the sideline and it will be incomplete.
Now a player falling OOB must meet the control and 2 feet and then maintain control after he hits the ground. Now a certain troll will use this as an example as to why Dez's catch was overturned, when it does not apply because a player going OOB will not and can not make a football move to complete the process.
The end zone: A player must have control and 2 feet in bounds. Again you will find case plays where a foot lands on the sideline. Now a player falling in the end zone must control the ball through contact with the ground. Now our neighborhood troll will say see Dez's play was incomplete. Again what football move is to be made in the end zone?
Then you will see case plays in the field of play: The 8.9 play that our rule misuser keeps writing has an airborne player catching a pass and going directly to the ground. Of course item 1 applies because in this case only part A of the 3 step process is met. You will find case plays where one foot is down. You will find case plays where 2 feet are down. But the one thing they all have in common is that A-C were not met before the player hit the ground.
Then there is case book play 8.12 from the last Official NFL Case Book: This case book includes 8.9 as well, but of course joefrl has not read it, he only used the few examples in the Rule Book and not all possible scenarios where Item 1 is used.
8.12 says a player catches the ball in 2 hands and lands on 1 foot, is contacted by the defender which causes him to go to the ground, after starting to the ground he gets a 2nd foot down, he then braces himself with his right arm and pushes off his 2nd foot down and lunges for the end zone. Ruling COMPLETED CATCH. This case play is important for three reasons. One, it establishes that the A-C process still applies to a player going to the ground. Two, that the A-C process does not have to occur before the fall starts. Three, the play is almost identical to what happened in GB. In fact the differences in GB make it even more of a catch. Unlike the case play Dez landed on two feet, so at that point both A and B were met. At that point Dez turns his body toward the end zone and takes a step. This is critical because a turn and step establish part C. But it does not end there, Dez also switches the ball from two hands to one. A player still catching a ball will not do that will they? No, that also establishes part C. From this point the Dez play mirrors the case play with an arm down to brace and a lunge toward the goal line, again completing the A-C catch process and making Item 1 moot.
In anticipation of the ignoring response:
The one area where I agree to a certain extent is how wordy the rules are and the fact that 8.12 was not in the rule book examples was a mistake in the rule book, but does not mean it still did not apply.
There were no rule or point of emphasis changes to the catch rules in 2013 or 2014 so the case plays in the 2012 case book still applied. Which is supported by the Blandino video in this thread, as well as the comments including a football move from both Blandino and Seratore after the game.
