stadium noise has not become a factor now for the steelers. If you didn't notice they switched to a silent snap. idk what the "loudest stadium" is. I was under the impression that it was Indy, but either way denver and indy are both at the top. So the noise isn't really a factor anymore.
Also the steelers are flying up to denver tomorrow I believe. They'll be pretty ajusted to the elevation by sunday.
Coaching is going to be the single most important factor in the game. The steelers beat the colts because they out coached them. Tons of pressure on defense, and they stuck to a simple offense. I wouldn't be surprised if they whipped out new trick plays on denver too. either way it's going to be a good game. the steelers have an excelent rush defense thats going to match well with denvers rushing offense.
