"In the fourth quarter, they got to 135.4, and that's where we thought they were going to finish," Robertson said. "Heads dropped, but then the fans really started working together."
The result was a record-setting din that shook the stadium's press box.
"We were really trying hard to get our calls to each other on defense. It was really tough," Chiefs safety Eric Berry said. "I had to actually go up to some of my teammates and yell in their ear what the calls were. But we love it, man. That's a great feeling."
Chiefs coach Andy Reid said he felt the ground shaking, and quarterback Alex Smith said he had a hard time communicating with teammates on the sideline when the crowd was at its peak.
Always when the Raiders had the ball, of course.
"The way the crowd was going, that was tough," Smith said. "I was sitting there on the sideline, and I could tell, it was hard environment to execute in."
Did he feel just a little sorry for Pryor trying to make his calls?
"Not at all. I've had my fair share of those," Smith said with a smile. "But I don't know if I've seen anything like that. That was pretty special."
