I actually don't think its a stupid rule....if you try to catch the ball and it hits the ground....it shouldn't be a catch. I was outraged by calvins because he lost control after he was trying to get up off the ground...which should have been a "different football move" all together. Dez had it, went to the ground, and the ball was sliding all over the place on the ground....that's not a catch imo.
But if they consider Dez making a football move and it still touches the ground, its a good catch I believe.
