You know, scrubbing that video above kind of changes my mind on this. Pause it at 4 seconds and then scrub watching the RT and the ball. He moves as soon as the center moves the ball, but the rest of the line doesn't move until the ball is halfway to Mahomes. The top of his helmet is also right at the waistline of the center. If you look at the OL, Taylor is the only one who's looking at the ball in the center's hand. He can do that because he's lined up so far back. The rest of them are going by sound. Light travels much faster than sound. I've been screaming about this all day, but Taylor may actually be in the right here.
