When did the ball hit the ground? His hands were still around the ball when it touched the ground. That is possession. He never lost possession.
The ball hit the ground, when he stretched out. He didn't drop the ball and it hit the ground. It hit the ground and popped out as he was going down.
Now if they were crediting him for his football moves, and the ball popping out like that, then it's a catch and a fumble that doesn't count as a fumble cause the ground can't cause a fumble.
But I'm saying that how the NFL is going to explain this, so they can say it's the right call, is that he didn't take three steps and lunge forward in the act of football moves. They're going to say he was falling to the ground, after coming down, and in that case he must maintain control of the ball, all the way through the end of the play. So when he stretched out, and the ball, while against his forearm, contacted the ground and popped out they're going to say he lost control of the catch and it doesn't count.
That's the way it will be explained.
It's not the correct call. He clearly caught the ball, came down to the ground with possession, took three steps and turned his body to lunge at the endzone. Those are all football moves after making the catch. But the league isn't going to admit that cause they're not going to admit to two major blown calls on consecutive weeks in the playoffs.
They're going to say he never came down and made a move they're going to say he came to the ground and fell and since he was falling down he has to maintain control throughout.
