than the common sense rule when it comes to making a catch. You basically have to not only possess it with two feet down, but also keep possession after you hit the ground. If you bobble it when you hit the ground, it's not a catch. Even though the Oakland receiver had two feet and a hip down on the ground in the end zone, when his elbow hit, he bobbled the ball and it brushed the ground. Therefore, in the NFL that's not a catch. I don't agree with it, but that's the rule.
