He looks frozen in time. I'll bet he's one of those guys who didn't get it 'right' in practice twice in a row, and a coach got all in his ear with direction. So they're trying to sell this play, it busts, he has no idea, hears the coach's voice recording playing in his brain, and just keeps doing what he was told to do. Of course, when the plays busts, no need to keep selling it.
