It's a pretty straight-forward rule. If you don't have possession through the entire completion when you go to the ground, it's not a catch. It's not a new rule and wasn't a terribly difficult call for the refs. The only question, as they said, was whether there was a second move. There clearly wasn't, so the call was upheld. Give me a break. He caught the ball, hit the ground, and flipped it up. Saying anything else in blatant homerism. I've seen that call many times in college and the NFL. It's not a new rule. This just happened to be an extreme instance of it. Honestly, there's no way I'd interpret that he had control all the way through the ground.
