2014 Item 1 did not contain upright long enough, and that concept did not appear anywhere else within the 2014 rules. Post GB, your boy, specifically used a football move in his explanation of the Dez play and not once did he say Dez was not upright long enough to make a move, he said he did not make enough of a move.
By the wording of the 2015 rule, the catch process needs to be completed before going to the ground, which did not happen in the play he used to illustrate the correct way to lunge by a play Dez made against NY. Dez completed the catch process after falling in that NY game, which completely contradicts the upright long enough added in 2015.
