The ball was thrown where only two individuals could have caught the ball, and both were Seahawks. 49'ers were completely blocked out of the play. The defenders are on the outside of where the ball was delivered. You cannot make a play in the end zone from behind the receiver unless the ball is really under thrown, because if you notice this ball was slightly under thrown and Rogers still couldn't do anything about it . This might be okay in the open field as tight coverage, but in the end zone it's blown coverage. The receivers did not simply outrun the defense, the play was planned and they probably even targeted Rogers as they were only bringing him in as a 4th defender due to injury.
