It actually does get pretty loud. I live in Arizona and my friend has season tickets so I've been to a few games and heard it get loud. This will be a tough game.
On another note, my friend was telling me they're only going with 3 DB's..he seemed concerned about that..he said their OLine is shaky right now due to some injuries. Daryl Washington suspension hasn't even been lifted yet..he was suspended all of last year.
