Based on the official reason given as to why it wasn't reviewed I'm of the opinion, going by the screenshots I took frame by frame, he did get his second foot down in the end zone while still in possession of the ball. So it should have been reviewed IMO.
1. There's no way to tell from you last image if he is still in possession of the ball or if it has started moving out of his grasp already. 2. Close calls happen in every game. -- their dreams a tattered sail in the wind
