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. Receivers do that all the time. He caught the ball, got both feet/knees down, and flipped the ball up. The play ended when he got the 2nd knee down.
