That was my exact argument immediately after the game when a receiver is going to the ground he's got to hang onto the ball and a football move doesn't necessarily trump that. Lost track of how many argued with me over this.
Count me, for one. Even though they applied the "going to the ground" rule to overturn the catch, Dez wasn't going to the ground to make the catch.
The problem is that there is no standard definition of what constitutes "going to the ground," so there is no distinction made between a receiver diving to catch a ball; and a receiver catching a ball, taking three steps, and falling. It was correctly ruled a catch and down by contact on the field. This is why Fisher (also on the competition committee) was talking about one standard on the field, and another for the replay. That's what has to be fixed, which means--not changing any rules--but putting a definition of "going to the ground" into the rule book that is
not open to interpretation.
To remove the element of subjectivity, they could make "going to the ground"
not taking at least two steps heel-to-toe. IOW, if the receiver gets two feet down
flat (no toe-taps, no sides of feet brushing the ground) with control of the ball, it's a catch and he's now a runner. If the ball comes loose when he hits the ground, it's a fumble. If he was contacted, he's down by contact.
That way you "idiot-proof" it, and you don't have a PR clown like Blandino inserting his own interpretations.
