I rest my case. You have absolutely no understanding of how rules and case plays work, none, zip, nada.
It did not say that at all. If going to the ground was the dominate part of the rule, don't you think prior to 2015 a simple sentence of, "The catch process must be complete before a player catching a ball begins going to the ground?" The case play says you can complete it after you start going to the ground, which is EXACTLY how the rule was written in 2014. As for specific case play wording, you want a case book 5 million pages in length? Because that would be what it would take to have every possible scenario covered. To officiate you have to be able to connect the dots by seeing how things fit together. How many types of going to the ground catches have there been? We have had them on the sidelines, endzone, field of play, with 1 foot, two feet, three feet down, control from the start, control in the middle, no control at all, with contact, without contact, and on and on. There were three case plays in the case book on going to the ground, THREE. By your logic if a play doesn't exactly fit those three plays it is useless....WRONG. One supplied, ONE POSSIBLE SCENARIO FOR, never becoming a runner and containing control. One supplied, ONE POSSIBLE SCENARIO FOR, for the time element to become a runner making maintaining through the ground unnecessary. The third supplied, ONE POSSIBLE SCENARIO FOR, a football act, bracing to lunge, as an element to becoming a runner again ending the ground requirement.
I find it laughable that you guys keep saying how fixated we are on the rule book, while all along using it as the backbone of a flawed argument. You care to know why we keep bring the case play and the rule changes up? Because they supply FACTUAL EVIDENCE that the misapplied the rule in GB and then re-worked the rule in 2015 to erase that mistake.
